Detailed explanation-1: -Bioaccumulation. Selective absorption and concentration of elements or compounds by cells in a living organism, most commonly fat-soluble compounds. Biomagnification.

Detailed explanation-2: -The term bioaccumulation is short for biological accumulation.

Detailed explanation-3: -Bioaccumulation occurs when toxins build up-or accumulate-in a food chain. The animals at the top of the food chain are affected most severely. This is what happens: Small amounts of toxic substances-often pesticides or pollution from human activity-are absorbed by plants.

Detailed explanation-4: -Bioaccumulation is a process of accumulation of chemicals in an organism that takes place if the rate of intake exceeds the rate of excretion. Chemicals are introduced into the organism through exposure to the abiotic environment (soil, water, air) or as dietary intake (trophic transfer).

Detailed explanation-5: -Bioaccumulation is the gradual accumulation of substances, such as pesticides or other chemicals, in an organism. Bioaccumulation occurs when an organism absorbs a substance at a rate faster than that at which the substance is lost or eliminated by catabolism and excretion.
