Answer Details

In the carbon cycle, carbon dioxide in the air may be replenished by respiration. This is the process by which living organisms take in oxygen and release carbon dioxide as a waste product. During respiration, carbon dioxide is released back into the atmosphere, increasing the amount of carbon dioxide in the air. This process occurs in all living organisms, including plants and animals, and is a natural part of the carbon cycle.
