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

Earthquakes release phosphorus.

Phosphorus is carried in the rain that was evaporated from lakes.

Human use of fertilizers release phosphorus into the groundwater.

Phosphorus is transpired from the leaves of plants.

Earthquake releases phosphorus.

Explanation:

Phosphorus cycle is a biogeochemical cycle that show how phosphorus move in the environment.

Phosphorus is first released in the phosphorus through weathering of rocks and Earthquake. Rock is the major source of phosphorus. Phosphorus moved to the soil through water.

The plants absorbed phosphorus in the soil and use it for growth.

Animals consume plants and obtain phosphorus from them.

When plants and animals die, decomposition occur by the activities of bacteria which release it to the environment.

Human use of fertilizers releases phosphorus into ground water.

Explanation:

This method is an artificial way of phosphorus entering the phosphorus cycle.

Phosphorus cycle involves the washing down of phosphorus from weathered rocks then plants absorba it and it later decomposes, and it continues to repeat the process.

So also, the use od some certain chemicals and fertilisers like NPK (Nitrogen, Phosphorus, Potassium) is a man made method of phosphorus entering the cycle.
