Answer:
All types of living organisms use cellular respiration for the production of energy from food molecules such as glucose.
Explanation:
Respiration is energy releasing process which occurs in mitochondria of the cell. Respiration has two types i. e. Aerobic and anaerobic respiration. In aerobic respiration, energy is released from the breakdown of glucose molecules with the addition of oxygen while anaerobic respiration is the release of energy from breakdown of glucose molecules without the use of oxygen.
