Question 20 • Biology

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

Answer
A
Earthquakes release phosphorus.
B
Phosphorus is carried in the rain that was evaporated from lakes.
C
Human use of fertilizers release phosphorus into the groundwater.
D
Phosphorus is transpired from the leaves of plants.

Explanation

Phosphorus can enter groundwater when rain or irrigation carries phosphorus from fertilizers through the soil. This makes human use of fertilizers a way phosphorus moves into the phosphorus cycle. Water evaporating from lakes and transpiration from leaves generally do not carry phosphorus into the atmosphere, and earthquakes are not the described route here.
