How does the phosphorous cycle differ from the nitrogen cycle and the carbon cycle? A.
The phosphorous cycle enters both water and atmosphere, unlike the nitrogen cycle and the carbon cycle.
B.
The phosphorous cycle occurs only in the atmosphere, unlike the nitrogen cycle and the carbon cycle.
C.
The phosphorous cycle does not enter the atmosphere, unlike the nitrogen cycle and the carbon cycle.

C.

Explanation:

The phosphorous cycle does not include an atmospheric component because phosphorous does not cycle through the atmosphere. In comparison, important processes of the carbon and nitrogen cycle occur in the atmosphere (compare three images below).

The phosphorus does not enter the atmosphere, unlike the nitrogen cycle and the carbon cycle

Explanation:

This is because the phosphorus cycle is different from all of the nitrogen and carbon cycle. This is why its ''C''
