Understanding Forest Structure
Forests are complex ecosystems that consist of diverse plant species and layers of vegetation. The correct answer, option 'B', highlights the hierarchical structure of forests, which is essential for understanding their ecology.
Layered Vegetation
- Uppermost Layer (Canopy):
- This layer is primarily made up of tall trees that form a dense cover. It plays a crucial role in absorbing sunlight and provides habitat for various wildlife.
- Middle Layer (Understory):
- Below the canopy, the understory consists of smaller trees and young saplings that thrive in the shade of the upper layer. This layer supports various species of birds and insects.
- Lowest Layer (Forest Floor):
- The forest floor is where shrubs, herbs, and ground cover plants grow. This layer is vital for nutrient recycling and provides habitat for small animals and insects.
Forest Dynamics
- Growth and Change:
- Forests are dynamic systems that continuously grow and change over time. They undergo processes like succession, where different plant species replace one another as the ecosystem matures.
- Regeneration Ability:
- Contrary to option 'C', forests can regenerate naturally after disturbances such as fires or logging, given that the conditions are favorable for growth.
Importance for Communities
- Lifeline for Communities:
- Forests provide resources like wood, food, and medicinal plants to forest-dwelling communities, supporting their livelihoods and cultural practices.
In summary, option 'B' correctly describes the structured layers of vegetation in forests, emphasizing their ecological complexity and importance to both biodiversity and human communities.

Features of Desert Plants
Desert plants have adapted uniquely to survive in harsh environments characterized by extreme temperatures and limited water availability. Let's analyze the given statements:
Statement A: Leaves of some plants take the shape of spines.
- This statement is true.
- Many desert plants, like cacti, have modified their leaves into spines to minimize water loss through transpiration.
- Spines also provide protection from herbivores.
Statement B: Photosynthesis in cactus plant is usually carried out by leaves.
- This statement is false.
- In cacti, the leaves are reduced to spines, and photosynthesis is primarily conducted by the stems, which are green and capable of photosynthesis.
- This adaptation helps the plant conserve water while still performing vital functions.
Statement C: Roots of most desert plants go very deep into the soil for absorbing water.
- This statement is true.
- Many desert plants have extensive root systems that can reach deep into the ground to access moisture that is unavailable to surface-level plants.
- Some plants also have shallow roots that spread widely to capture rainwater quickly when it does occur.
Conclusion
Given the analysis, the correct answer is option 'C' because:
- Statements A and C are true, while statement B is false.
- Therefore, the option that includes both true statements (A and C) is the right choice.
Understanding these adaptations is crucial for appreciating how desert flora has evolved to thrive in extreme conditions.

Tanuja Mishra answered |
Extended Family:
- An extended family is used in a broader sense than a joint family.
- The extended family is a family that consists of parents, children, uncle, aunt, grandparents, their relatives etc.
Joint Family:
- A family which lives together with all family members up to the second generation like grandparents, parents, uncle, aunts and their children is called ajoint family.
- Such a type of family arrangement is especially common in India.
Nuclear Family:
- A nuclear family consist of a couple and their children(1 or more).
- It is also known as elementary family or conjugal family or small family.
Single Parent Family:
- Single-parentfamilies are families with children under age 18 headed by aparentwho is widowed or divorced and not remarried, or by aparentwho has never married.
- In such types of families, children live with only one parent.
Thus, Sitamma's family is a Joint family.
Mistake Points
- A family that lives together with all family members up to the 2nd generation such as grandparents, parents, uncles, aunts and their children are called a joint family.
- An extended family comprises almost every blood relative, parents, grandparents, uncles, aunts, cousins and possibly spouses.

Aditya Nair answered |
Assertion (A): Decomposers and Their Role
Decomposers are essential organisms in ecosystems that play a critical role in nutrient cycling. They break down dead organic material, such as fallen leaves, dead animals, and other organic waste.
- Enrichment of Soil:
- Through decomposition, nutrients like nitrogen, phosphorus, and potassium are released back into the soil.
- This process enhances soil fertility, allowing plants to grow better.
Reason (R): Vultures as Decomposers
Vultures are scavengers that feed on dead animals, but they are not classified as traditional decomposers.
- Feeding Behavior:
- Vultures consume carrion (dead animals), helping to clean the environment.
- However, they do not break down organic material at a microscopic level.
- Role of True Decomposers:
- True decomposers, such as fungi and bacteria, perform the chemical breakdown of organic matter.
- They facilitate the recycling of nutrients in the ecosystem.
Conclusion: Understanding the Relationship
- Both (A) and (R) are true statements.
- However, (R) does not correctly explain (A) because vultures do not enrich the soil directly; they merely consume dead animals.
Thus, the correct answer is option 'B': Both (A) and (R) are true, but (R) is not the correct explanation of (A).

EVS is a subject which is concerned with nurturing children's curiosity about the natural environment.
Students are taught EVS at primary level because:
- to connect learners to the natural and socio-cultural environment
- exploring their surroundings and getting connected.
- developing awareness about environmental and social issues.
- to promote plurality of texts and contexts.
- for building capacity for critical thinking and problem-solving.
- nurturing the curiosity and creativity particularly with the natural environment.
- locating and comprehending relationships between the natural, social and cultural environment.
Hence, we conclude that acknowledging the superiority of textbook knowledge over actual observation is not the aspect of EVS.

Joint Family:
- A family which lives together with all family members up to the second generation like grandparents, parents, uncle, aunts and their children is called a joint family.
- The most aged man is the head of the family.
- Such a type of family arrangement is especially common in India.
- The joint family is an extension of the nuclear family (parents and dependent children)
- The size of the joint family is large, consisting of an older man and his wife, his sons and unmarried daughters, his sons’ wives and children, and so forth.
- All the family members love each other and motivate for any work.
- Due to elders in the family, children learn discipline at an early age.
- These types of families are usually found in village areas where big families stay together.

Weeds in Fields
Removing weeds from the field is crucial for maximizing crop production. Weeds compete with crops for essential resources like water and nutrients, which can hinder the growth and development of the desired plants. Therefore, it is important to control and manage weeds effectively to ensure optimal crop yields.
Effects of Weeds
Weeds reduce the production of fields by utilizing water and fertilizers that are meant for the crops. This competition for resources can lead to stunted growth, lower yields, and overall reduced productivity of the field. By removing weeds, farmers can ensure that their crops receive the necessary resources for healthy growth and maximum output.
Conclusion
In conclusion, weeds are unwanted plants that grow in fields without being planted. They have a negative impact on crop production by competing for essential resources. Therefore, it is essential to remove weeds from fields to prevent them from affecting the growth and yield of crops.

Sanjana Chavan answered |
Understanding the Correct Answer: Silkworm
Silkworms, specifically the larvae of the silk moth (Bombyx mori), possess a remarkable ability to locate potential mates over considerable distances using their sense of smell. This capability is primarily due to the following factors:
1. Pheromone Detection
- Silkworm females release specific chemical signals known as pheromones into the air.
- Males can detect these pheromones from several kilometers away using their highly sensitive antennae.
- This adaptation is crucial for reproduction, as it allows males to find females even in dense environments.
2. Sensory Adaptations
- The antennae of silkworm males are equipped with specialized sensory receptors.
- These receptors respond to the chemical composition of the pheromones, enabling precise detection.
- This biological design enhances their ability to locate a mate, ensuring the continuation of their species.
3. Importance in Reproduction
- The ability to find females from long distances increases mating opportunities.
- Successful mating is essential for the lifecycle of silkworms, as they are cultivated for silk production.
- Farmers and breeders often rely on this natural behavior to optimize breeding programs.
Conclusion
In conclusion, silkworms are uniquely adapted to find their female counterparts using chemical cues. This distinguishes them from earthworms, flatworms, and tapeworms, which do not possess the same level of olfactory capabilities for mate detection. Understanding these biological traits is essential in the context of their ecological and economic significance.

Vaibhav Menon answered |
Explanation:
- Nocturnal birds: Nocturnal birds are birds that are active during the night. They have specially adapted eyes that allow them to see well in low light conditions. This enables them to hunt for food and navigate in the dark.
- Black and white vision: Nocturnal birds typically have monochromatic vision, which means they see in black and white. This type of vision helps them to detect movement and contrast in low light situations.
- Fast flying: Nocturnal birds, such as owls and nightjars, are known for their fast and agile flight. This allows them to quickly catch their prey in the darkness.
- Adapted for night: These birds have evolved to have keen hearing and silent flight to aid in their nocturnal activities. Their feathers are designed to dampen sound, making them stealthy hunters.
In conclusion, the boy likely observed a nocturnal bird with black and white vision flying swiftly through the night, showcasing its unique adaptations for hunting and survival in low light conditions.

Constructivism is centered on the idea that human knowledge and learning are actively constructed by the learner, not passively received from the environment. Knowledge is always someone's knowledge. It is created or constructed by the experiencing individual. It is not impersonal or absolute.
Key Points
- The contents of EVS are organized thematically.
- Topics of both social studies and science are integrated.
- A teacher needs to combine two or more subject areas into one lesson like integrate the concepts and issues of science, social science, environmental education to teach EVS in anintegrated manner.
- The syllabus of EVS for class 3rd and 5th integrates the concepts and issues ofscience, environmental education, and social sciencebecause children look at their environment in a holistic manner and couldn't differentiate any topic between'environment studies', 'science', and 'social science'.
- Transacting EVS (integrated themes) requires teachers to move beyond the individual boundaries of disciplines (their own subject specializations) and plan appropriate learning experiences to help children synthesize multiple perspectives and develop integrated concepts.
- Considering the dynamic nature of children’s learning, the NCF, 2005 has emphasized the concept of dynamic assessment. This is yet another challenge, as it demands teachers to gather more knowledge about how children think, understand, and relate to the environment, what difficulties they encounter, how they carry out EVS activities and projects, etc.
Hence, we conclude that as a constructivist teacher preparing a lesson plan integrated with science, social science and environmental studies constructively is the best plan for integrated EVS.

Concept:
- Humans carry seeds from one place to another, knowingly or unknowingly.
- People bring the seeds of plants that they find beautiful or useful, to grow in the garden.
- Later the seeds of these plants spread to other places.
- Many years later people may not even remember that these plants did not grow there earlier.
Explanation:
Vegetables and their country of origin:

Environmental studies describe the interrelationships among organisms, the environment and all the factors, which influence life on earth, including atmospheric conditions, food chains, the water cycle, etc. It is a basic science about our earth and its daily activities, and therefore, this science is important for everyone.
Pedagogical principles in teaching-learning of EVS :
- Active participation of children is important in constructing knowledge. Opportunities should be given for observations using a variety of learning resources such as visits to parks, museums, water bodies, and various places in the community. If learning occurs beyond the walls of classrooms, the quality of learning is better.
- Efforts should be made by teachers to relate the child’s local knowledge to the school knowledge - this would discourage rote memorization and encourage developmentally age-appropriate learning in EVS.
- Children in early grades learn through a variety of ways, therefore opportunities should be given to explore, observe, draw, categorise, discuss/ speak, ask questions and enlist, etc. to develop various skills /processes.
- Pictures /illustrations play a very important role in EVS learning as these support the written material.
- Activities and questions play an important role as these provide opportunities for children to express themselves.
- Each child learns at his /her own pace. The challenge before the teacher is to handle multilevel groups so as to address the needs of children including the differently challenged group of children. Teachers should design activities for these children in such a manner so that they can be engaged meaningfully while doing activities with their peer group.
- Assessment for learning (formative assessment), should be used as an inbuilt part of the teaching-learning process so as to identify and address learning gaps in a timely manner.
- The real purpose of assessment of learning (summative assessment) is not to compare the progress of children but to track the progress of each child regularly. This assessment should be done periodically by using a variety of modes (not restricted to the written mode only).
- The teacher should maintain a portfolio of each child and this document should be used as an ‘assessment tool’ to know the progress of each child over a period of time.
- Teachers must understand that learning is a mutual process. Children learn from each other and a teacher also learns from children, particularly to understand their needs.
- EVS learning is also concerned with the inculcation of important values/ attitudes and appreciation. It fosters an appreciation of the interrelationship between all living organisms and their environments and encourages children to become active agents in the conservation of the environment.
- EVS learning cultivates respect for cultural diversity and sensitizes children regarding minorities and people with special needs. Prejudices and discrimination are challenged, while respect and mutual understanding are promoted.
Hence, we conclude that o
ne of the important pedagogical principle of environmental studies is the use of the environment as a learning resource.

The syllabus of EVS has been developed within a child-centered perspective of themes that provide a common interface of issues in social studies, sciences, and environmental education.
Important Points
- ‘Plants’ and ‘Animals’have consciously been included under the theme of‘Family and Friends’to highlight how humans share a close relationship with them and to also provide a holistic and integrated scientific and social perspective of studying them.
- The theme ‘Family and Friends’, especially through its two sub-themesRelationships and Work and Play, allows children to look at their own body as part of their‘self’in a more contextual and connected manner.
Key Points
The syllabus for Classes III-V is woven around six common themes given below;
the predominant theme on Family and Friends encompasses four sub-themes:
- Family and Friends:
- Relationships
- Work and Play
- Animals
- Plants
- Food
- Shelter
- Water
- Travel
- Things We Make and Do
The syllabus web moves outward over the three years; it gradually extends the child’s understanding of her world, beginning from the immediate
‘self ’
to include her family, the neighborhood, the locality, and also the country
. Thus by the time the child reaches Class V, she can see her ‘self ’ in the larger context
– as part of a community, the country, and also, more tacitly, as located in this world. Hence, we can conclude that in the above situation, the teacher should explain to the child how plants helps us in our daily life.

Concept:
The family life cycle:
- The family life cycle adopts a longitudinal view of family life.
- It is based on the recognition of successive phases and patterns as they happen over the years.
- The family life cycle generally consists of seven stages.
Explanation:
Early family:
- A married couple without children.
- It is the stage of family founding.
- The first stage begins with the establishment period.
- It all starts with marriage and lasts until the first child is born.
Thus, early family
is the first stage of the family life cycle.
Additional Information
Other stages of the family life cycle:
- Second stage: Child-bearing family.
- Third stage: Family with preschool-age children.
- Fourth stage: Family with school-age children and adolescents.
- Fifth stage: Family launching young adults into higher education/work.
- Sixth stage: Middle-aged parents with grown-up/married children.
- Seventh stage: Ageing couple—retirement to death of both spouses.

EVS is a
multidimensional subject
which covers important principles from various academic fields.- NCF recommends bothintegrated and thematic approaches for EVSlearning at the primary level to nurture the curiosity and creativity of the child, particularly with the natural environment.
Key Points
In primary level, Environmental Studies is integrated with Social Studies and Science because at early childhood:
- children look at their environment in a holistic manner.
- children couldn't compartmentalize any topic into 'science' and 'social science'.
- children are not mature enough to interpret the aspects of science and social science in a graded manner.
Important Points
- Integrated approach:
- EVS in the primary level is visualized as an integrated approach as the EVS syllabus has been made in an integrated manner includingscience,andsocial studiesas well.
- It helps children to explore and connect to their surroundings.
- EVS in the primary level is visualized as an integrated approach as the EVS syllabus has been made in an integrated manner including
- Thematic approach:
- EVS in the primary level is visualized as a thematic approach as the entire EVS syllabus is connected and integrated within a theme.
- It makes learning more natural and comprehensible for a better understanding of children.
- EVS in the primary level is visualized as a thematic approach as the entire EVS syllabus is
So, from the above-mentioned points, we conclude that in primary level, Environmental Studies is integrated with
Social Studies
and Science.

About Gregor Mendel:
- Gregor Mendel, a 19th-century Augustinian monk.
- He was born in a poor farmer’s family in Austria in 1822.
- He is called the father of modern genetics.
- He found that the pea plant has some traits which come in pairs (called an allele).
- Mendel's pea plant experiments conducted between 1856 and 1863 established many of the fundamental laws of heredity.
- It is now referred to as the laws of Mendelian inheritance.
Gregor Johann Mendels Theory:
- Mendel used a number of contrasting visible characters of garden peas- round/wrinkled seeds, tall/short plants, white/violet flowers, and so on.
- He took pea plants with different characteristics- a tall plant and a short plant, produced progeny from them and calculated the percentages of tall or short progeny.
Thus, the correct answer is Gregor Mendal.
Additional Information
Darwin Theory:
- Darwin gave the theory of natural selection.
- Each species reproduces to maintain its race.
- The species struggle for survival with changing environmental conditions.
- The species adapts with the surroundings survives and rest extinctions.
MS Swaminathan:
- He was a geneticist.
- He is remembered as he had introduced a high-yielding variety of wheat.
- Book "The Quest for a World Without Hunger" was released by Prime Minister Narendra Modi on MS Swaminathan.
George Mestral:
- In 1948, one day George Mestral came back from a walk with his dog.
- He was amazed to find seeds sticking all over his clothes and on his dog’s fur.
- He wondered what made them stick.
- So he observed these seeds under a microscope.
- He saw that the seeds had many tiny hooks which got stuck to clothes or fur.
- This gave Mestral the idea of making Velcro.
- He made a material with similar tiny hooks that would stick.
- Velcro is used to stick together many things – clothes, shoes, bags, belts and many more.

A syllabus is a kind of instructive tool that sets a standard of what is expected to be achieved by the students during the complete course in a specified period of time.
- A syllabus actually serves as the contract between the students and the teachers which contain functions and ideas that are used for the assessment of the student's performance.
Key Points
- This syllabus web has been developed within a child-centered perspective of themes that provide a common interface of issues in social studies, sciences, and environmental education.
- The National Curriculum Framework 2005 has re-emphasized the recommendation of NCF 2000 that Environmental Studies should be taught as an integrated course for the entire primary stage.
- It is important for a teacher to be acquainted with the organization of the syllabus in order to better understand and use the textbooks.
- Environmental Studies at the primary stage is perceived as an approach to learning about the environment in its totality without being burdened by any disciplinary considerations.
- The NCERT syllabus attempts to reflect the above realization and understanding in a number of ways:
- The syllabus is organized not as a list of “topics” but as “themes”. And, each theme has a few sub-themes.
- The sub-themes are organized in a spiral and progressive manner with an emphasis on integration.
- The sub-themes allow for a connected and interrelated understanding to develop.
- The themes in the syllabus do not begin by listing key concepts, or rather key questions which allow each child to think, apply, and develop his/her own understanding and articulate their own learnings and ideas.
- The thematic approach helps to bring in perspectives from different subjects and disciplines.
- The activities are only suggestive and can be easily adapted to suit the local situations.
Hence, the syllabus of EVS based on the NCF 2005 is designed to provide an integrated perspective that draws upon insights from sciences, social sciences, and environmental education.

Environment refers to the conditions or surroundings in which a person, animal, or plant resides or operates. The environment is a combination of natural and human-made phenomena. While the natural environment refers to both biotic and abiotic conditions existing on the earth.
Key Points
- The environment is physical, geographical, and biological. It includes both living and non-living components.
- The environment has been expanding and changing over time. In the earliest times, the environment was limited to the biological communities found in the air, water, and land on the planted ground. As time passed, man enlarged his environment through his social, economic, and political functions.
- There are several connections between the environment and the economy, including the fact that it acts as a sink for pollution and waste.
- The political environment includes political conditions such as overall stability and peace in the country.
The environment is made up of physical, biological, and cultural components that are connected in a variety of ways both individually and collectively. These components can be described as follows:
- Physical elements:Space, landscapes, water bodies, climate, soils, rocks, and minerals are examples of physical elements. They determine the irregular nature of the human environment, as well as its possibilities and limitations.
- Biological components:The biosphere is made up of biological components like plants, animals, microbes, and people.
- Cultural components:The economic, social, and political components that makeup culture are essentially man-made aspects.
Hence, from the above-mentioned points, we can conclude that
A, B, C, and D are correct.

Environmental Studies is the study of the environment in the context of earth and living things. It is more concerned with the scientific attitude to explore, investigate, and develop an understanding of our natural, human, social and cultural dimensions of local and wider environments.
Key Points
Social studies are concerned with human study in relation to the socio-cultural environment. Our society means our surroundings include all the entities around us such as land, air, water, sunlight (natural environment) culture, society, school, college, family (social environment), etc.
- Social Science is the study of relations of humans with society and their social life. It is taught at the school level for promoting healthy social/ democratic living among learners. It aims at enabling students to adjust to their socio-cultural environment which includes family, community, state, nation, and at large the entire humanity.
Therefore, it can be concluded that subjects from the socio-cultural context help students to understand the society in which they live.

The syllabus for EVS (classes III-V) is thematic in approach rather than being structured around individual topic/s (as it used to be in the earlier years). It is woven around six common themes – Family and friends, Food, Shelter, Water, Travel, and Things we make and do.
Key Points
- These themes provide real-life links to the children’s daily experiences.
- Thematic organization of content in EVS helps dissolve the conventional subject boundaries created in the formal education system.
- It also encourages the learner to realize the linkages between the various subjects.
- Thematic structuring of the contents in EVS cuts across the boundaries of several disciplines such as social sciences, sciences, languages, history, geography, civics, etc., developing in children an interdisciplinary perspective (contributions of various disciplines) to understanding environment and environmental problems and their solutions because this is related to our lives and lifestyles.
- EVS, thus, is an interdisciplinary study of how humans interact with their environment – physical, biological, social, and cultural.
Thus, it is concluded that
A, B, and C are the correct options.

Key Points
Objectives of Environmental Education at Primary Level
- To know and understand the true aspects of the environment in general.
- To know and understand the interaction between mammals, between human and their environment and interaction between the various elements and components of the environment.
- Build understanding, awareness and sensitivity towards causes and efforts of the class that continuously take place in society the world around us.
- To build and develop skills in thinking, reasoning, enquiring, evaluating and making decisions concerning human and the world around them.
- Inculcate the attitude in using the knowledge and skills towards solving problem and issues related to individuals, society and the environment.
- To build the values and attitudes towards the need and necessity to live together in harmony in the context of the heterogeneous society
Objectives of Environmental Education at Secondary Level
- To emphasize the relevance of science to daily life.
- To develop a scientific attitude in student.
- To create an environment conducive to greater reliance on the use of principles and practices of science.
- To acquaint the students with various natural phenomena.
- To develop an outlook that emphasizes the method employed in different disciplines of science.
Confusion Points
It should be noted that understanding interrelationships of human with the rest of the world is not the objective of EVS education, because EVS aims to develop sensitivity of surrounding, while understanding 'rest of the world' is too vast term to use.
Hence, we conclude that u
nderstanding the interrelationship of humans with the rest of the world is not the objective of environmental education.

Concept:
- Insects have different senses.
- They can see, hear, taste, smell and feel.
- Some animals can see their prey from far away.
- Some can hear even the faintest sound.
- Some insects can find their friends by their smell.
Explanation:
- As the ants move, they leave a smell on the ground.
- The other ants follow the smell to find the way.
- The smell is recognised and identified by the members of the same group only.
- An ant thus uses its smell as an identity proof.
Thus, the ant knows that the other ants were not from its group through their smell.

- Different birds have different types of vision.
- The type of vision they have depends on their source of food.
Explanation:
Monocular vision:
- Birds with eyes on the sides of their headshave a wide visual field.
- It is useful for detecting prey.
- Such birds can focus on two different things at a time.
- When they look straight ahead, both their eyes focus on the same object.
- They don't have to move their heads to see around.
- They can see four times as far as we can.
- Example: Kites, Eagles, Vultures.
Binocular vision:
- While those with eyes on the front of their heads have binocular vision.
- Such birds can estimate distances when hunting.
- They have to move their heads to see around.
- The binocular vision of birds makes themsee distinctly.
- Example: Owl, Crows, Doves, Peacock, Nightingales, Parrots, Pigeons etc.
Thus, Kites, Eagles and Vultures can see up to 8 meters away.

Concept:
- Carnivorous plants obtain essential nutrients from the heterotrophs.
- These plants trap insects and obtain the nutrients they do not get from the soil.
- They are not called heterotrophs or consumers because they only derive nutrients from insects.
- These plants get energy from the process of photosynthesis.
- Hence they are both producers and carnivores.
Explanation:
Nepenthes is a plant that:
- It can trap and eat frogs, insects and even mice.
- It is found in Australia, Indonesia and Meghalaya in India.
- It has a pitcher-like shape, and a leaf covers the mouth.
- It has a special smell that attracts insects, which get trapped and can't get out.
Thus, the correct answer is Meghalaya.

EVS is a subject that is concerned with the development of learners' awareness of environmental issues. Principles refer to a set of guidelines that govern and effectively direct the educational process.
Key Points
- Learning without burden.
- Simple to complex approach.
- Use of audio-visual materials.
- Individual differences of the child.
- Activity and experience-based learning.
- Encouragement of use of various sources.
Hence, we can conclude that students’ parents' income is not covered in the principles of organizing teaching-learning of EVS.

Concept:
Individualism:
- Individualism is characterised by a lack of interpersonal ties and self-reliance.
- Individualistic cultures are those that put the needs of the individual before the needs of the group.
- In this kind of culture, people are seen as independent and autonomous.
- A person's opinions and preferences frequently influence their social behaviour.
Explanation:
Both (A) and (B):
Westernization:
- Western civilization is frequently regarded as individualistic and its inhabitants as having a more independent sense of self.
- A person is thought to be essentially composed of personal characteristics like personality traits, attitudes and beliefs.
The imagination of free life-style:
- Individualists place a strong emphasis on the idea that family members should be able to solve issues or achieve goals independently, without the need for others' help.
- People are viewed as "excellent" in individualistic families if they are robust, self-sufficient, outspoken, and independent.
Thus, the i

At the primary level, Environmental Education (EE) is introduced as Environmental Studies (EVS). EVS for classes III to V deals with the study of our environment (physical, biological, and socio-cultural) with an emphasis on its preservation and conservation (NCF 2005).
- EVS, at the primary stage, is an integrated subjectarea that draws uponinsights from sciences(physical, chemical, and biological), social studies (history, geography, political science, sociology, etc), andenvironmental education(protection and conservation).
- It helps children connect with their natural and human-made environmentand in understanding our dependence on the various components of the environment (biotic, abiotic, and human-made).
- Also, It helps children develop a holistic understanding of their environmentincluding the socio-cultural environment.
- Further, It helps children in maintaining a multidisciplinary perspective to the understanding of our environmental issues/problems and appreciate the impact/s of our daily activities on its integrity.
Hence, we conclude that Environmental studies derives from both science and social science.

The environment generally refers to the surroundings of an individual, including social and the natural environment, for example, culture, school, family, land, water, air, etc.
- At the primary level, children must be taught through an integrated approach rather than teaching in parts. At the primary level, we shouldn't teach students the concepts in isolation.
- We should teach them concepts and processes in an integrated manner to explore the other aspects of a specific subject matter and find the connection among them.
Key Points
Environmental studies:
- It includes the study of the relationship of humans with other aspects affecting their life
- It also studies how humans can contribute positively to bring the desired changes in our environment.
- It emphasizes the development of a scientific attitude so that students can develop their own concepts of the environment.
- It is more concerned with the scientific attitude to explore, investigate, and develop an understanding of our naturally occurring environment.
- Social Studies and Social Science together constitute the Environmental Studies which are generally taught at the primary level through integrated and thematic approaches.
Hint
Therefore, it is concluded that environmental studies deal with the interrelationships of human beings with their environment and include their contribution to bringing desirable changes in their surroundings.

Explanation:
Earthworm:
- The earthwormis a reddish-brown terrestrialinvertebrate.
- They inhabitthe upper layer of themoist soil.
- During day time, they live in burrows made by boringandswallowingthesoil.
- Earthworms play a vital role in the natural cycle of the earth.
- The Earthworms soften the soil by digging underneath to make tunnels.
- They play a crucial role in breaking down organic matter and fertilising the soil,simply through their constant eating and pooping.
- Earthworms can be used for fishing and compost.
- Worms are important to the ecosystems in which they live and breed.
- They are known as farmers friends as their compost helps in enriching the soil and give bountiful produce.
- Kingdom: Animalia
- Phylum: Annelida
- Class: Clitellata
- Family: Lumbricidia
Important Points
Earthworms are useful in several ways for farmers:
- Earthworms make the soil porousby digging burrows in the soil. Hence they are calledfriends of the farmers.
- The nitrogenous wastes and other waste products of the earthworms form food for plants. This process of increasing the fertility of the soil by earthworms is called vermicomposting.
- Earthworms are used as fish bait to catch fish.
- Some tribals in India use earthworms as medicine to cure jaundice, piles, diarrhoea, bladder stones, etc.
- The earthworms reduce both acidity and alkalinity of the soilandcreate optimum conditions for plant growth.
- The density of earthworms in the soil is considered to be a good indicator of healthy soil because they increase the soil's water-holding capacity and moisture content.
Thus,
A) Earthworms soften the soil of the field in which they live by digging the soil underneath. - Correct
B) The tunnels dug by earthworms provide easy passage for air and water into the soil. - Correct
C) The earthworms eat the weeds and save the main crop. - Incorrect
D) The earthworms eat the dead leaves and plants. The dropping of the earthworms make the soil more fertile - Correct.

Environmental studies or EVS is
the study of the environment in the context of earth and living things. It is more concerned with theAt the primary level
, children must be taught through an integrated approach
rather than teaching in parts. At the primary level, we shouldn't teach students the concepts in isolation. We should teach them concepts and processes in an integrated manner so that they could explore the other aspects of a specific subject matter and could find the connection among them.
Key Points
- At the primary level, social studies and social science are taught in an integrated manner as Environmental Studies (EVS)which includessix themes: family and friends, food,shelter, water, travel,things we make and do.
- The textbook of environmental studies at the primary level is based on these themes which refer tothe thematic approach.It is also known as amulti-disciplinary approachwhere many concepts/topics are being taught in a collective manner.
- The primary level students must be taught about theirimmediate surroundings first(family, school, neighborhood) andthen about their wider surroundings(society, community).
- If we teach them social studies and social science separately, they will not be able todevelop the inter-related understandingthat is needed to develop aninsight over a specified conceptwhich may include various components of the environment.
- So, in order to develop divergent thinkingand to understand each and every component of a particular matter students need to be taught in an integrated manner.
So, "transport" is not
the main theme of the thematically designed curriculum of EVS at the primary level.A child can learn EVS from physical, biological, chemical, social, cultural and other dimensions. This statement endorses that EVS is a- a)Contextual Area
- b)Composite Area

Environmental Studies at the primary level possesses some special characteristics that other subjects do not possess.
Key Points
- Composite: It is visualized as a composite study area drawing learning experiences/contents from physical, biological, chemical, social, cultural, and other dimensions of study. The contents are organized around curricular themes like Food, Shelter, Water, Travel, etc. This thematic organization is intended to correlate two or more disciplines of study or school subjects.
- Contextual: The context for EVS is the environment. Since the environment differs from place to place, the examples, events, and practices used to teach environmental understanding will differ. A dated event in human history and the associated details and explanations will remain the same whether it is being discussed in a hill station or in a coastal town.
- Learner-Centered: It means that children’s learning forms the core of the classroom transaction rather than teaching. This is based on the view that each child comes to school with his/her own perception and understanding of the world around. The child correlates this basic understanding with objects and experiences in the environment as he/she goes along in his/her journey and expands his/her knowledge base.
- No Right, No Wrong: Since teaching-learning of and for ‘Environment’ are contextual. Hence, no single viewpoint or opinion may remain valid in all situations.
- ‘Values’ are an Integral Component of EVS: There are some universally accepted values (for example, we should save forests), then, there comes those values which relate to the (social and natural) environment, the process of upbringing, her beliefs and faith (social) system, etc. together.
Hence, it could be concluded that the above-mentioned statement endorses that EVS is a Composite Area.

Concept:
- Nutrition is a process by which an organism consumes and uses food materials.
- There are various modes of nutrition mainly, Autotrophic, Heterotrophic, Chemoautotrophic, Saprophytic,etc.
- Parasitismis a type of heterotrophic nutrition.
Explanation:
Cuscuta:
- < />Cuscutais aparasitic plant.
- Since Cuscutadoes not have chlorophyll,it cannot synthesize its own food by photosynthesis.
- It takes readymade food from the plant on which it is climbing.
- The plant on which it climbs is called a host.
- Since it deprives the host of valuable nutrients, it is called a parasite.
- It is yellow and tubular in structure twining around the stem and branches of a tree.
- Other parasitic plants are - Rafflesia, Viscum, Nuytsia floribunda.
- Parasitic plants cause damage to the host plant.
Thus, Cuscuta is a parasite.
Additional Information
- Holophytic or autotrophic nutrition:In this type of nutrition the organisms prepare their food by themselves. Eg - green plants.
- Saprobiotic nutrition:In this type of nutrition the organism depends on the dead and decaying matter of other organisms. Eg - fungi
