Detailed explanation-1: -This process is known as “biomagnification.” When contaminants found in small amounts at the bottom of the food chain biomagnify, they can pose a significant hazard to predators that feed at the top of the food chain.
Detailed explanation-2: -This is also referred to as biological magnification. The chemical substances include certain toxins, heavy metals, mercury and other harmful products at a higher concentration. As these substances increase and accumulate, it moves up in the food chain.
Detailed explanation-3: -Some POPs could have half-lives of years or decades and they can stay in the environment until they are taken up by plants and animals. POPs can bioaccumulate in the fatty tissue of living organisms and, therefore, become concentrated as they move through the food chain.
