Phosphorus Cycle: The biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere, playing a crucial role in the growth of living organisms.

Eutrophication:

The process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen, negatively impacting aquatic life.

Nutrient Limitation: A condition in which the growth of organisms is restricted due to insufficient availability of essential nutrients, such as phosphorus or nitrogen.
