Question

Which describes a way in which phosphorus may enter into the phosphorus cycle?

Answer 1

Humans use of fertilizers release phosphorus into the groundwater.

Answer 2

The phosphorus cycle refers to a biogeochemical cycle, which illustrates the movement of phosphorus via the hydrosphere, lithosphere, and the biosphere. Unlike various other biogeochemical cycles, the atmosphere does not play a substantial function in the movement of phosphorus.

Phosphorus primarily comes from the rock and soil on the Earth and is recycled by the living species.
