Detailed explanation-1: -The ways in which an element-or compound such as water-moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

Detailed explanation-2: -Biogeochemical Cycle of Oxygen Photosynthesis is a biochemical process where oxygen is generated from carbon dioxide processing and released as energy. The oxygen that is released makes its way into the atmosphere where it is breathed in by various animals.

Detailed explanation-3: -Answer and Explanation: The two biological processes most important to the carbon cycle are photosynthesis and cellular respiration.

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