Detailed explanation-1: -Biomagnification, also known as bioamplification or biological magnification, is the increase in concentration of a substance, e.g a pesticide, in the tissues of organisms at successively higher levels in a food chain.

Detailed explanation-2: -The increase in the concentration of harmful substances, such as pesticides, in the body of living organisms at each level of a food chain is called biological magnification. Chemical substances such as pesticides are sprayed over crop plants to protect them from pests and diseases.

Detailed explanation-3: -Biomagnification happens when toxic chemicals, like DDT, whose remains in the environment are consumed indirectly by organisms through food. When an organism in the higher food chain consumes the lower organism containing such chemicals, the chemicals can get accumulated in the higher organism.

Detailed explanation-4: -Biomagnification, also known as bioamplification or biological magnification or bioaccumulation, is the increasing concentration of a substance such as a toxic chemical in the tissues of organisms at successively higher levels in a food chain.
