Question

Discuss the importance of air.

Answer 1

Oxygen (a component of air) is needed for respiration. The animals that live both on land and even the aquatic animals need oxygen to exist. Air is the fundamental building block, apart from which life itself would not exist.

Some main important use of air:

1. Oxygen present in the air is needed for proper respiration.
2. Plants perform the process of photosynthesis due to the presence of carbon dioxide in air.
3. Air is necessary for burning.
4. Oxygen helps in oxidizing the food eaten by organisms to release energy.
