The correct statement about the phosphorus cycle is:

B.The phosphorus cycle utilizes the processes of erosion and weathering.

Here's a breakdown of each option:

A.Phosphorus enters the atmosphere as phosphates: This is false. Phosphorus typically does not enter the atmosphere in the form of phosphates. It mostly exists in the soil and water as phosphate ions (PO₄³⁻), but it does not become part of the atmosphere in significant amounts like carbon, nitrogen, or sulfur.

B.The phosphorus cycle utilizes the processes of erosion and weathering: This is true. Phosphorus is primarily released from rocks through the processes of erosion and weathering. Once released, it is available for uptake by plants and other organisms.
