Biological Magnification, also called bioaccumulation -- is the process whereby certain substances such as pesticides or heavy metals move up the food chain.

These substances work their way into rivers or lakes, and are eaten by aquatic organisms such as fish, which in turn are eaten by large birds, animals or humans. The substances, called bioaccumulants, become concentrated in tissues or internal organs as they move up the chain.

It occurs when compounds are poorly excreted by an organism thereby leading to a buildup of said compound as the organism consumes more and more organisms/substances containing the compound.

Define biological magnification and explain why humans are often more severely affected?

Biological magnification: the process by which pollutants become more concentrated in successive trophic levels of a food web (accumulation of pollutants in fatty tissues of a predator) Humans are often more severely affected than earlier trophic levels due to biological magnification. The ppm (parts per million) is the unit of measurement for concentration of chemicals like pollutants and augment to a degenerative degree in higher trophic levels. Humans are consumers and higher in the food web, thus subject to the malicious effects of biological magnification of toxins.

What causes excessively high levels of toxic chemicals in fish-eating birds?

Example of biological magnification?

An example of biological magnification can be seen when pesticides work their way into the streams and lakes. These toxic chemicals are ingested by fish and other aquatic organisms. When the fish and aquatic organisms are eaten by birds, humans, and other animals they are working their way through the food chain and can have hazardous effects.

What organism is effected most by biological magnification?

biological magnification:The increasing concentration of toxins from pesticides, herbicides, and various types of waste in living organisms that accompanies cycling of nutrients through the trophic levels of food webs.I myself am I trying to find the answer to this question, I believe that biological magnification increases with an increase in trophic level. If a snail eats grass that has been sprayed by pesticides, the snail is poisoned, then a mole eats the snail, the mole is poisoned. This continues until the tertiary consumer itself is infected with the worst strain of the poison/toxin.
