Biomagnification factor
Webcalled biomagnification. Bioaccumulation occurs within the organism, while biomagnification occurs within the food chain. Factors such as water pH, mercury concentration in the water, water temperature, and biodiversity all affect whether and to what extent bioaccumulation occurs. Procedure: Warm-Up: Discuss with students what … Biomagnification is the buildup of concentration of a substance (x) in a food chain. For example the DDT concentration in parts per million increases with trophic level. Concentrations build up in organism's fat and tissue. Predators accumulate higher levels than prey.
