WebTell students that there are two more concepts they should understand to grapple with this issue: bioaccumulation and biomagnification. These concepts will also help them complete the Food Web Infographic element of their final project. 4. Introduce the concepts of bioaccumulation and biomagnification. 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. Biological magnification often refers to the … See more Biomagnification, also known as bioamplification or biological magnification, is the increase in concentration of a substance, e.g a pesticide, in the tissues of organisms at successively higher levels in a See more Although sometimes used interchangeably with "bioaccumulation", an important distinction is drawn between the two, and with bioconcentration. • Bioaccumulation occurs within a trophic level, and is the increase in the concentration of a … See more Two common groups that are known to biomagnify are chlorinated hydrocarbons, also known as organochlorines, and inorganic … See more • Fisk AT, Hoekstra PF, Borga K,and DCG Muir, 2003.
