Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which 2 biogeochemical cycles depend directly on photosynthesis?
A
the hydrologic cycle and the oxygen cycle
B
the carbon cycle and the phosphorous cycle
C
the nitrogen cycle and the phosphorous cycle
D
the oxygen cycle and carbon cycle
Explanation: 

Detailed explanation-1: -Respiration, combustion and decomposition are three other ways that CO2 and/or oxygen is released back into the atmosphere. Another biogeochemical cycle, the hydrogen cycle, connects some of the pathways in nature that are involved in the carbon and oxygen cycles.

Detailed explanation-2: -Chemical energy to organisms within the ecosystem. Which two biogeochemical cycles depend directly on photosynthesis? The oxygen cycle and the carbon cycle.

Detailed explanation-3: -Hence the oxygen and the carbon dioxide level in the atmosphere is balanced by the respiration and the photosynthesis.

Detailed explanation-4: -The carbon cycle Plants take in carbon dioxide from the atmosphere during photosynthesis, converting it from inorganic carbon to organic carbon. Animals get carbon by eating plants or by eating other animals.
