Question

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.

Answer 1

The most common form of entry of the phosphorus is by human use of the fertilizers which is released into the groundwater.

Most of the fertilizers being used in agriculture contains nitrogen and phosphorus which is carried to the aquatic ecosystem through surface runoff. When the tropical rainforest are cut down by humans and fertilizers are being used in large amounts the nutrients stored in plants or rocks are washed by the heavy rains and they reach groundwater or other water bodies. Therefore, the humans alter the natural phosphorus cycle majorly in several mentioned ways.

Answer 2

According to the context, phosphorus may enter into the phosphorus cycle by humans that use fertilizers into the groundwater.

What is the phosphorus cycle?

It is the circuit that describes the movement of phosphorus within a given ecosystem.

Thanks to terrestrial water currents and the water cycle, part of the phosphates are stored in seas and oceans, fertilizers provide excellent nutrition to the soil, this is washed by rainwater or irrigation, draining into water deposits , rivers or the sea.

Therefore, we can conclude that according to the context, phosphorus may enter into the phosphorus cycle by humans that use fertilizers into the groundwater.
