Class 6 Science Chapter 6 Important Question Answers - The Living Organisms - Characteristics and Habitats

Very Short Answer Type Questions

Q1: What is an organism?
Ans: An organism is any living thing.

Q2: Give an example of a terrestrial habitat.
Ans: Forest.

Q3: Name one adaptation of desert plants.
Ans: Reduced or spiny leaves.

Q4: What do fish use their gills for?
Ans: Fish use their gills to absorb oxygen from water.

Q5: What is acclimatization?
Ans: Acclimatization is small adjustments by the body to overcome short-term changes in the environment.

Q6: Define habitat.
Ans: Habitat is the natural place where an organism lives and grows.

Q7: What is the purpose of streamlined bodies in fish?
Ans: Streamlined bodies reduce friction and allow fish to move freely in water.

Q8: Why do plants have tiny pores on their leaves?
Ans: Plants have tiny pores on their leaves to help them breathe (exchange gases).

Q9: What is respiration in living organisms?
Ans: Respiration is the process of breathing in oxygen and releasing carbon dioxide.

Q10: Give an example of a plant's response to a stimulus.
Ans: Touch-me-not plant closing its leaves when touched.

Short Answer Type Questions

Q11: Explain the term "habitat" and provide an example of an aquatic habitat.
Ans: Habitat is the natural environment where organisms live. An example of an aquatic habitat is a pond.

Q12: How do animals in the grasslands adapt to their environment?
Ans: Animals like lions in grasslands have brown skin for camouflage, strong claws for hunting, and eyes in front of their head for better prey detection.

Q13: Why is respiration important for living organisms, and how do plants respire differently from animals?
Ans: Respiration is important for obtaining energy. Plants respire by taking in carbon dioxide and releasing oxygen during the day, unlike animals that release carbon dioxide.

Q14: Describe one characteristic that distinguishes living organisms from non-living things.
Ans: Living organisms respond to stimuli in their environment, while non-living things do not.

Q15: Explain the process of excretion in living organisms.
Ans: Excretion is the elimination of waste from the body. Plants eliminate waste through secretions like resins and gums, while animals have specialized organs for excretion.

Long Answer Type Questions

Q16: Discuss the adaptations of desert plants and animals for their habitat.
Ans: Desert plants have reduced or spiny leaves, deep roots, and a thick waxy layer to minimize water loss. Desert animals like camels have long legs for mobility and can store water in their humps.

Q17: Explain the importance of respiration in living organisms. How do aquatic animals, like fish, respire differently from terrestrial animals?
Ans: Respiration is crucial for obtaining energy from food. Fish have gills to extract oxygen from water, while terrestrial animals, like humans, breathe in oxygen from the air.

Q18: Discuss the characteristics that all living organisms share and provide examples to support your explanation.
Ans: All living organisms need food, show growth, respire, respond to stimuli, reproduce, and eventually die. For example, plants grow and reproduce through seeds, animals respond to environmental changes, and all living things need food for energy.

Q19: Explain the concept of adaptation in living organisms. Provide examples of adaptations in both terrestrial and aquatic habitats.
Ans: Adaptation refers to features or habits that help organisms survive in their environments. In terrestrial habitats, desert plants have spiny leaves, while aquatic fish have streamlined bodies and gills for oxygen absorption.

Q20: Discuss the role of excretion in living organisms. How do plants and animals differ in their excretory processes?
Ans: Excretion is the elimination of waste from the body. Plants excrete substances like resins and gums, while animals have specialized excretory organs. This process helps maintain the health of living organisms by removing harmful waste products.
