The phosphorus cycle reflects the harmonious interactions between organisms and their biotic and abiotic environments. Phosphorus continually flows through each compartment&—rocks and soil, water, and living organisms—allowing living organisms and humans to exist and prosper. In Unification Thought, this represents circular motion. Circular motion occurs when their are give and receive actions, with phosphorus being exchanged between each compartment.
The harmony is sometimes disrupted by human beings, who may use fertilizer excessively, resulting in more phosphorus in the environment than the system is prepared to handle under its existing homeostasis. As a result, eutrophic conditions can be created, which results in decreased biodiversity.
