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

The following choices are provided;

  • Earthquakes release phosphorus.
  • Phosphorus is carried in the rain that was evaporated from lakes.
  • Human use of fertilizers releases phosphorus into the groundwater.
  • Phosphorus is transpired.

The answer is; Earthquakes release phosphorus

Phosphorus is usually made less available to plants and to the rest of the ecosystem through runoffs. The washed-off phosphorus is deposited at the oceans- and seabeds with sediments. This phosphorus is made available again due to tectonic plate movements. Tectonic movements may cause earthquakes that expose these sediments to the earth’s surface.This uncovers the sedimentary rocks to agents of weathering and hence the elements are more available to living organisms on the surface.
