A pollutant is a substance or energy introduced into the environment that has undesired effects, degrading environmental quality.

Biological magnification is the process by which pollutants increase in concentration as they move up the food chain.
Trophic transfer occurs when pollutants are passed from one species to another through the food chain.

Eutrophication is the process by which excess nutrients, such as phosphorus and nitrogen, in water bodies stimulate excessive plant growth, depleting oxygen and harming aquatic life.
