What is bio-magnification

Asked by  | 14th Jul, 2009, 03:16: PM

Expert Answer:

Biomagnification is a cumulative increase in the concentration of a persistent substance in successively higher trophic levels of the food chain. For example, if an organism is eaten by another organism, these substances move up the food chain and become more concentrated at each step.

Biomagnification of a toxic substance has the potential to cause harm to organisms, particularly to those at the top of the food chain.
