The phosphorus cycle is a
natural cycle that occurs through rocks, water, soil, sediments, and other
organisms found on Earth. Phosphorus is a natural chemical compound found in
soil; rain and other forms of weathering causes the release of this compound in
the environment. Plants absorb phosphorus from the soil and in turn are consumed
by animals and humans. This chemical compound is an essential form of nutrient
that is responsible for cell development both in humans and animals.

Unlike the carbon cycle,
the phosphorus cycle does not need the involvement of human activity for it to
occur. But humans take advantage of this naturally occurring process through
farming. Humans apply phosphate fertilizers to their crops in various farmlands. </span>
