The phosphorus cycle moves nutrients through an ecosystem primarily through the weathering of rocks, which releases phosphate ions into the soil and water. Plants absorb these phosphates, incorporating them into organic molecules, which are then consumed by animals. When organisms excrete waste or die, phosphorus returns to the soil or sediment, where it can be recycled or leached into water bodies, continuing the cycle. Unlike other nutrient cycles, phosphorus does not have a gaseous phase, making its movement more localized and slower.
