The phosphorus cycle differs from the biogeochemical cycles in that a. It does not have an atmospheric reservoir b. It does no have an oceanic reservoir c. There is no assimilation of phosphorus d. There is no decomposition of phosphorus

The phosphorus cycle differs from other biogeochemical cycles like water, nitrogen and carbon cycle because it does not have an atmospheric reservoir or as states in a. Unlike any other cycles, the atmosphere is not included in its processes or the route. Thus, phosphorus can not be found in a gaseous state. It can only be found in water, sediment and land.
