Answer» Bioaccumulation is the build-up of chemicals inside of living organisms. The two causes of bioaccumulation are the amount of the chemical coming into the living organism faster than the organism can use it and the living organism not being able to break down or excrete the chemical. Biomagnification is a cumulative increase in the concentrations of a persistent substance (e.g. pesticides, metals, etc.) as it moves up the food chain. This occurs when agricultural, industrial, or human waste pours into the ocean directly or via rivers, sewage, etc. Bioaccumulationrefers to the accumulation of a toxic chemicalin thetissue of a particular organism. Biomagnificationrefers to the increased concentration of a toxic chemical the higher an animal is on the food chain. |
