What is respiration in Class 7?

In Class 7 biology, respiration is explained as the process by which living organisms break down food to release energy needed for life activities. It is a basic life process that occurs in all plants and animals.

This process involves taking in oxygen, using it to break down food (glucose) inside cells, and releasing energy along with carbon dioxide and water.

The energy released is used for functions such as growth, movement, repair, and maintaining body functions.

In simple terms, respiration for Class 7 level means the process of releasing energy from food in living organisms.
