The global phosphorus cycle is called a "cycle," yet it has no atmospheric component. Phosphorus weathers from rocks and enters the soil. Once phosphorus is incorporated into plants or animals, how is it returned to the rock phase?
What will be an ideal response?
Decomposers return the phosphorus from dead animal and plant bodies back to the soil, where it combines chemically with water to form phosphates; it may then be bound into sediment and eventually reincorporated into rock through geologic activity.
