Explanation:

During cellular respiration, organisms uses oxygen for breakdown of food molecules such glucose and carbondioxide gas is released in the atmosphere. Respiration is a process in which energy is produced in the form of Adenine tri phosphate (ATP) and releases carbondioxide by the chemical combination of glucose and oxygen molecules. The type of respiration in which oxygen is used is known as aerobic respiration.
