Phospherus Cycle apes U1

What is the phosphorus cycle?

The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.

What are the main processes of the phosphorus cycle?

The main processes include weathering, absorption by plants, animal ingestion, decomposition, and sedimentation.

What role do plants play in the phosphorus cycle?

Plants absorb phosphorus from the soil, which is essential for their growth and is incorporated into organic molecules.

How does phosphorus return to the soil?

Phosphorus returns to the soil through the decomposition of organic matter, where it becomes available for uptake by plants again.
