what do you mean by respiration?
Respiration is a chemical process in which energy is released from food substances, such as glucose - a sugar.

The term "respiration" refers to two separate processes, both of which occur in living things and are related to the generation of energy. One is physiological respiration, the process by which an organism takes in oxygen and excretes carbon dioxide. The second is cellular respiration, a series of biochemical reactions that allow a cell to generate energy.
