Back

The process by which phosphorus moves through the environment, primarily through rocks, soil, water, and living organisms.

Front

Back

A process where water bodies become overly enriched with nutrients, leading to excessive growth of algae.

Front

Back

Photosynthesis, respiration, decomposition, and combustion.

How do human activities impact the nitrogen cycle?

Back

Through the use of fertilizers, which can lead to nutrient runoff and eutrophication.
