Question

The phosphorus cycle differs from the biogeochemical cycles in that
it does not have an atmospheric reservoir.
it does not have an oceanic reservoir.
there is no assimilation of phosphorus.
there is no decomposition of phosphorus.

Answer 1

The phosphorus cycle differs from other biogeochemical cycles primarily in that **it does not have an atmospheric reservoir**. Unlike cycles such as the carbon or nitrogen cycles, which include significant gaseous phases in the atmosphere, phosphorus primarily exists in solid form and is usually found in rocks, soil, and sediments, and is not present in the atmosphere in significant amounts.
