$Food+Oxygen\to Carbondioxide+Water+Energy$

• A. It is caused by the decay of organic substances.
• B. It is an important process in the nitrogen cycle.
• C. It is an essential process of aerobic respiration in living organisms.
• D. It is carried out only by green plants and certain type of bacteria.

Answer 1

The correct option is C It is an essential process of aerobic respiration in living organisms.

Respiration is the process in which the food substrate is broken down to produce energy. In the aerobic respiration, respiration is carried out in the presence of oxygen, where carbon dioxide and water are released as products. This is an essential process in all the living organisms for the production of ATP, which provides energy to carry out all the activities taking place in the cell.

Thus, the correct answer is option C.
