Biomagnification

The video tutorial explains biomagnification, a process where the concentration of a substance increases in the tissues of organisms across different levels of a food chain. Using mercury as an example, it describes how this toxic chemical is released into the environment and transformed into methylmercury, which is absorbed by small marine organisms. As these organisms are consumed by larger animals, the mercury concentration increases, leading to higher levels in top predators. The video also discusses bioaccumulation, the buildup of chemicals in organisms, and the adverse effects of biomagnification on wildlife and humans, including reproductive issues in seabirds and the impact of pesticides.
