What term describes the process by which certain toxic substances become increasingly concentrated in the tissues of organisms at progressively higher levels of a food chain?

Explanation

Biomagnification describes the process by which certain toxic substances, such as some pesticides or heavy metals, become increasingly concentrated in the body tissues of organisms as they move up progressively higher levels of a food chain, since predators at higher levels typically consume many prey organisms that have each already accumulated some amount of the toxic substance. This process means that top predators within an ecosystem, including humans in some cases, can end up accumulating notably higher concentrations of certain harmful substances than were originally present in the environment at lower levels of the food chain. This phenomenon has historically raised significant environmental and public health concerns regarding the use and long-term environmental persistence of certain chemicals.
