Class 4 Science Question Answers - Living Things

Q1: What are the two main categories of things in our surroundings mentioned in the text?
Ans: The two main categories of things in our surroundings are living things and non-living things.


Q2: Explain the key characteristics that distinguish living things from non-living things.
Ans: Living things have several key characteristics: they move, respire, are sensitive to touch and changes in their environment, grow, reproduce, and fulfill their nutritional requirements through processes like digestion. Non-living things, on the other hand, do not possess these characteristics. They do not move, respire, grow, or reproduce.


Q3: How do living things obtain energy to perform their functions?
Ans: Living things obtain energy through the process of Cellular Respiration. This process involves breaking down food to release energy that cells use to perform their functions.


Q4: Can you name some examples of living things mentioned in the text?
Ans: Examples of living things mentioned in the text include animals, birds, insects, and human beings.


Q5: Describe the process of reproduction in living things.
Ans: Living things are capable of producing offspring of their own kind through the process of reproduction. During reproduction, genetic information is passed from the parents to the offspring, ensuring that the new life is of the same species.


Q6: What is the main characteristic that distinguishes non-living things from living things?
Ans: The main characteristic that distinguishes non-living things from living things is that non-living things do not possess life. They lack cells, do not grow, do not respire, and do not reproduce.


Q7: Provide examples of non-living things mentioned in the text.
Ans: Examples of non-living things mentioned in the text include stones, pens, books, cycles, and bottles.


Q8: How do non-living things "grow," according to the text?
Ans: Non-living things "grow" by accretion. This means that they increase in size by adding materials externally. For example, a snowball may grow in size as more snow accumulates on its outer surface.


Q9: Explain why non-living things are considered immortal.
Ans: Non-living things are considered immortal because they do not have cells with a definite lifespan. Unlike living things, they do not undergo the cycle of birth, growth, and death.


Q10: What fundamental life processes are absent in non-living things?
Ans: Non-living things lack fundamental life processes such as reproduction, nutrition, excretion, and the ability to respond to stimuli. These processes are essential characteristics of living things.
