Chapter: 01. Living And Non Living Things

⁠

Question 1

The breathing organ in part (a) is stomata, in part (b) is gills, and in part © is the nose and lungs.
Aquatic animals, such as fish, use the breathing organ shown in part (b), which are gills.
Breathing is essential for all living organisms because it allows them to take in oxygen from the air or water, which is necessary to release energy from food, and to give out carbon dioxide, a waste product.

Question 2

Two living things are the tree and the dog. Two non-living things are the park bench and the red ball.
The dog is a living thing because it can move on its own (chasing the bird) and it breathes.
The non-living things shown, like the park bench and the red ball, are human-made. They were manufactured by people and are not found in nature in that form.

Question 3

The characteristic of living things best illustrated by this sequence of pictures is growth.
This characteristic is different in a non-living thing like a toy car because a toy car does not grow internally by itself. Any increase in its size would be due to external additions or modifications made by a human, not a natural process from within.
Besides plants, animals also show growth. For example, a puppy grows into a dog, or a human baby grows into an adult.

Question 4

The important characteristic of living things shown in these pictures is reproduction.
The two different methods of reproduction depicted are egg-laying (shown by the bird, where offspring hatch from eggs) and giving birth to live young ones (shown by the cat, which directly produces kittens).
No, a bicycle would not show this characteristic. A bicycle is a non-living thing and non-living things do not have the ability to reproduce or produce more of their kind.
