the process by which the concentration of toxic substances increases in each successive link in the food chain; also called [biological magnification]
The increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain. As a result of biomagnification, organisms at the top of the food chain generally suffer greater harm from a persistent toxin or pollutant than those at lower levels. Compare bioaccumulation.
