  Bioaccumulation • Bioaccumulation isthe build up of chemicals in the first organism in a food chain. The chemical build up could be from food intake, respiration, physical contact, etc. This results in the organism having a higher concentration of this chemical than its surrounding environment. An example of bioaccumulation is the build up of mercury in fish. Fish are the first organism to intake the mercury which is bioaccumulation. As the fish are eaten by organisms in higher atrophic levels, this is biomagnification.
