Bioaccumulation and Biomagnification

This Bioaccumulation and Biomagnification presentation also includes:

Ecology scholars consider the processes of bioaccumulation and biomagnification in the environment. As an example, DDT bioaccumulates in the fatty tissue of animals, resulting in reproductive failure and nervous system damage.
