The phosphorus cycle is the movement of phosphorus in the ecosystem. The cycle starts from the rocks which contain a lot of phosphorus compounds. As these rocks experience weathering, they break down and gets mixed into the ground. Sometimes it gets washed away in water. With this, plants are able to absorb P from the ground. The animals eat these plants and absorb P. The phosphorus returns to the soil through the wastes we release, and when the dead decompose. These then goes back to the process of the formation of rocks. Phosphorus cycle is a slow and unique cycle (Robson, 2017). Over the years, several human activities have affected the phosphorus cycle. The following are three ways on how these activities have an impact on the P cycle:
