Nipuns Institute answered |
Reasons to convince Roman not to cover the garden:
1. Fencing is good enough to stop animals from entering the garden:
- Fencing can effectively keep animals out and protect the plants.
- It is a less intrusive method compared to covering the entire garden with a shed.
2. Plants need fresh air and sunlight to produce their food:
- By covering the garden, the plants will be deprived of sunlight, which is essential for photosynthesis.
- Without sunlight, the plants will not be able to produce food and will eventually die.
3. Plants are the producers of the ecosystem:
- Plants play a crucial role in the ecosystem as they are the primary producers.
- They convert sunlight and carbon dioxide into oxygen and food, supporting other organisms in the food chain.
- If the plants die, the entire ecosystem will be disturbed, affecting the animals and birds that rely on the plants for food and shelter.
Conclusion:
- It is best not to cover the garden completely with a shed to allow the plants to thrive.
- Fencing can provide adequate protection while still allowing the plants to receive sunlight and maintain a healthy ecosystem.

Animals in Freshwater Ecosystems
Freshwater ecosystems are habitats that consist of bodies of water such as lakes, ponds, rivers, and streams. These ecosystems are home to a diverse range of plants and animals that have adapted to survive in these specific conditions. One common animal found in freshwater ecosystems is the frog.
Frogs in Freshwater Ecosystems
Frogs are amphibians that belong to the order Anura. They have a unique life cycle that involves living both in water and on land. Frogs start their lives as tadpoles, which are aquatic larvae, and then undergo metamorphosis to become adult frogs.
Adaptations of Frogs
Frogs have several adaptations that enable them to thrive in freshwater ecosystems:
- Moist Skin: Frogs have thin, permeable skin that allows them to breathe and absorb water through their skin. This adaptation helps them stay hydrated in freshwater environments.
- Webbed Feet: Frogs have webbed feet that aid in swimming and maneuvering in water. The webbing between their toes allows them to generate more propulsion in the water.
- Tadpole Habitat: Frog eggs are laid in water, and the tadpoles that hatch from these eggs spend their early life stages in freshwater habitats. They have specialized adaptations such as gills for breathing underwater.
- Food Source: Freshwater ecosystems provide a diverse range of food sources for frogs. They primarily feed on insects, small invertebrates, and sometimes even small fish.
- Camouflage: Many frog species have evolved camouflage patterns that help them blend into their surroundings and avoid predation.
Role of Frogs in Freshwater Ecosystems
Frogs play an important role in freshwater ecosystems as both predators and prey. They help control populations of insects and other invertebrates, contributing to the balance of the ecosystem. Additionally, frogs serve as a food source for larger predators such as birds, snakes, and mammals.
In conclusion, frogs are commonly found in freshwater ecosystems due to their unique adaptations and life cycle. They are well-suited to survive in these habitats and play a vital role in maintaining the balance of these ecosystems.

Why killing snakes is harmful to the ecosystem
Introduction:
Lakshmi Prasad, a small farmer, grows wheat on his land but is terrified of snakes. Whenever he encounters a snake, he kills it without considering the adverse effects on the ecosystem. As a nature lover, it is important to educate him about the importance of snakes in maintaining a balanced ecosystem.
Explanation:
1. Ecological role of snakes:
Snakes play a crucial role in the ecosystem. They help control the population of rodents and other pests, which can cause significant damage to crops like wheat. Snakes are natural predators of rats and mice, and by killing them, Lakshmi Prasad would unknowingly increase the population of these pests.
2. Impact on the food chain:
Snakes are an essential part of the food chain. They prey on smaller animals, thus maintaining a balance in the ecosystem. If snakes are killed, the population of their prey will increase, leading to an imbalance in the food chain. This can have cascading effects on other organisms and disrupt the overall ecosystem.
3. Increase in pest population:
By killing snakes, Lakshmi Prasad may inadvertently cause an increase in the population of pests like rats and mice. These rodents can destroy his wheat crop, resulting in significant economic losses. Therefore, it is important to make him aware that killing snakes would ultimately be detrimental to his own farming interests.
4. Promote alternative methods:
Instead of killing snakes, it is important to educate Lakshmi Prasad about alternative methods of dealing with his fear. For example, he can adopt snake repellents, create snake-friendly habitats away from his fields, or seek help from wildlife conservation organizations to safely relocate snakes if they pose a threat.
Conclusion:
In conclusion, killing snakes may seem like a simple solution to overcome fear, but it has severe consequences for the ecosystem. Educating Lakshmi Prasad about the ecological importance of snakes and promoting alternative methods will help him understand the importance of coexistence and the role snakes play in maintaining a balanced ecosystem.

Dhaval pandey answered |
Factors affecting desert ecosystems:
- Rainfall: Deserts are located in regions that receive very little rainfall, which is a crucial factor in determining the presence of desert ecosystems.
- Humidity: Due to extremely low humidity levels, desert ecosystems have limited water availability.
- Air pressure: While air pressure can affect weather patterns, it is not directly related to the presence of desert ecosystems.
- Water vapors: Although water vapors contribute to the overall humidity levels, they are not the primary determining factor for the presence of desert ecosystems.
Therefore, the correct answer is option D: rainfall. Desert ecosystems are located in regions that receive very less rainfall, resulting in low water availability and intense aridity.

Stoneridge Institute answered |
The consumers that eat both plants and animals are called omnivores.
Characteristics of Omnivores:
Examples of Omnivores:
Omnivores are a type of consumer that have a diverse diet and consume both plants and animals. They have the ability to obtain nutrients from both sources and are adaptable to a variety of food options. Here are some important characteristics and examples of omnivores:
Characteristics of Omnivores:
- Omnivores have a flexible diet and can consume a variety of plant and animal matter.
- They have both herbivorous and carnivorous adaptations in their digestive systems.
- They have a diverse set of teeth, including incisors for cutting and tearing and molars for grinding plant matter.
- They have a versatile digestive system that can break down both plant cellulose and animal proteins.
- They often have a broad range of habitats and can be found in various ecosystems.
Examples of Omnivores:
- Humans: We are a classic example of omnivores as we consume both plant-based foods (fruits, vegetables, grains) and animal-based foods (meat, fish, eggs, dairy).
- Bears: Bears have a varied diet that includes plants, berries, insects, fish, and occasionally small mammals.
- Pigs: Pigs are known for their ability to consume both plant matter and small animals or insects.
- Raccoons: Raccoons have a diet that consists of both plants (fruits, nuts) and animals (insects, small mammals, fish).
- Seagulls: Seagulls are opportunistic omnivores that eat both marine animals (fish, crabs) and plant matter (seaweed, berries).
In conclusion, omnivores are consumers that have the ability to eat both plants and animals. They play an important role in ecosystems by balancing the food chain and have adaptations that allow them to obtain nutrients from a diverse range of sources.

Yashina Kapoor answered |
To complete the food chain, we need to identify the organism that feeds on grasshoppers and is subsequently eaten by snakes.
The correct option is D: Frog. Here is the complete food chain:
- Plant: The food chain starts with plants, which are the primary producers. They use sunlight to produce food through photosynthesis.
- Grasshopper: Grasshoppers are herbivores that feed on plants, specifically on grass.
- Frog: Frogs are carnivores that feed on grasshoppers. They are secondary consumers in the food chain.
- Snake: Snakes are also carnivores and they feed on frogs. They are tertiary consumers in the food chain.
Summary: The complete food chain is as follows: Plant → Grasshopper → Frog → Snake.

Edgy Education answered |
The correct answer to fill in the blank is "temperature".
Explanation:
Desert ecosystems are characterized by specific environmental conditions that contribute to the sparse distribution of fauna and flora. Here's an explanation of each option and why "temperature" is the correct answer:
1. Temperature: Deserts are known for their extreme temperatures, with scorching hot days and freezing cold nights. These temperature variations create a challenging environment for organisms to survive.
2. Pressure: While atmospheric pressure does play a role in weather patterns, it is not a primary factor in determining the characteristics of desert ecosystems.
3. Volume: The volume of what is not specified in the sentence, so it cannot be determined if it is relevant to desert ecosystems.
4. Velocity: Velocity typically refers to the speed of an object in motion. It is not directly related to the characteristics of desert ecosystems.
In summary, the correct answer to fill in the blank is "temperature" because it accurately reflects the extreme thermal conditions present in desert regions.

- An animal that eats both plants and animals is known as an omnivore.
- Omnivores have adaptations that allow them to digest both plant and animal matter.
- Examples of omnivores include bears, humans, and pigs.
- The term "omnivore" is derived from Latin: "omni" meaning "all" or "everything" and "vorare" meaning "to eat."
- This dietary flexibility helps omnivores survive in various environments by allowing them to consume a wide range of foods.

It looks like you're presenting a food chain or food web. In this chain:
- Plankton serves as the primary producer or the first trophic level (often phytoplankton in aquatic ecosystems).
- Mussels are primary consumers (filter feeders that eat plankton).
- Fish are secondary consumers (predators of mussels).
- Whale represents a higher trophic level, often as a tertiary consumer or top predator.
