The provided text is a solution to a biology exercise. What was the original question for this exercise?

Here are the answers to the exercise questions:

A. Tick (✓) the correct option:

1. An example of a living thing is:
   • (a) tree
2. Fish breathe through their.
   • (c) gills
3. Which of these characteristics is shown by both living and non-living things?
   • (c) Weight
4. Clouds move in the sky. They are:
   • (b) non-living things
5. Living things that reproduce by laying eggs are:
   • (c) all of these

B. Fill in the blanks:

1. Living things need food to live and grow.
2. Living things use energy from the food they eat to grow.
3. Non-living things like clouds and cars can move but not on their own.
4. Mosquito eggs hatch into larvae.
5. Many plants shed their leaves in autumn and bear flowers in spring season.

C. Write 'T' for True and 'F' for False:

1. Plants breathe through tiny holes called gills.
   • F
2. Plants and animals are non-living things.
   • F
3. Non-living things reproduce.
   • F
4. Animals move on their own.
   • T
5. Green plants make their own food.
   • T

D. Answer the following questions:

1. Living things grow, breathe, need food, reproduce, move on their own, and respond to stimuli. Non-living things do not possess these characteristics; they do not grow, breathe, or reproduce on their own.
2. Animals move from place to place primarily to find food and water, seek shelter, escape from predators, and find mates for reproduction.
3. Plants breathe through tiny pores called stomata, which are mainly found on the surface of their leaves. These stomata allow for the exchange of gases like oxygen and carbon dioxide.
4. Reproduction is the biological process by which living organisms produce new individuals of their own kind. This ensures the continuation of their species.
5. Man-made things are objects or materials that are created or manufactured by humans, rather than occurring naturally in the environment. Examples include cars, buildings, and books.
