Respiration can be defined as the process by which exchange of gases takes place. Oxygen is inhaled inside the body and carbon dioxide is exhaled by the body into the outer environment.
Explanation:
When glucose is broken down and ATP production takes place in the mitochondria of the cells. To make ATP from glucose oxygen is required, and the leftover products are carbon dioxide and water. They are excreted from the body by blood stream and exhalation.
The waste product of humans and animals are carbon dioxide and water, that is aerobic respiration and as for anaerobic respiration it is lactic acid. Hope this helps
Decomposers also break down the bodies of dead organisms resulting in nitrogen being returned to the soil as ammonia. In some conditions denitrifying bacteria in the soil break down nitrates and return nitrogen to the air.
