Phosphorus is stored in rocks.
Weathering along with rain break down these rocks which results in the phosphorus to enter water and soil.

Animals that eat these plants or drink the water where the phosphorus has run off also absorb phosphorus.

Plants are able to absorb the phosphorus and then grow.

Humans have affected the phosphorus cycle by adding phosphorus to fertilizer to help plants grow. This can be neagtive however, because an over ubundance of phosphorus can result in the overgrowth of algee.

When these plants and animals die, decomposers are able to turn the phosporus inside them from organic matierial into inorganic matierial.
