Grade 10 Food Chains and Webs

Choose whether 'biomagnification' or 'bioaccumulation' best completes the sentence. Write the correct term in the blank.

                  Bioaccumulation                   describes the process by which toxins are taken up and held in an organism from either exposure to or by eating food containing the toxin.                    Biomagnification                    occurs when concentrations of toxins in an organism increase due to transfer through the food chain, and specifically from energy loss across trophic levels.
