Detailed explanation-1: -Cellular respiration and photosynthesis are biological processes in which matter and energy flow through the biosphere. These two processes are responsible for the exchange of oxygen and carbon dioxide between living organisms and the environment.

Detailed explanation-2: -Answer and Explanation: The two biological processes most important to the carbon cycle are photosynthesis and cellular respiration.

Detailed explanation-3: -1: Photosynthesis and Aerobic Respiration: Photosynthesis consumes carbon dioxide and produces oxygen. Aerobic respiration consumes oxygen and produces carbon dioxide. These two processes play an important role in the carbon cycle.

Detailed explanation-4: -On land, the major exchange of carbon with the atmosphere results from photosynthesis and respiration.
