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.
biological magnification is when biological matter is magnified.
when many ditergen get mix with water they cause biological magnification

Increasing biological magnification
Reducing monoculture, crop rotation, biological controls, the production of biodegradable pesticides and genetically engineering plants to produce their own pesticides are some solutions to biological magnification. Education about the impact of pesticides on the ecosystem and human health is also important.
The use of the pesticide DDT.
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.
we can solve the concentration of biological magnification if produce less DDT
(c) 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.
they can destroy the nutrients in soil thus creating dangerous plants which can be fatal to the animals that eat them
biological magnification -teddybearr
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.
eyepiece magnification times obective magnification
I think the Consumers are mostly affected due to the rapid growth of a substance in the chain.
either a or b. biological magnification or biomagnification. ((:
DDT is a prime example. It affected Gerbes (a water bird), who ingested fish contianing the toxins after they ate midges
total magnification=(magnification by ocular lens) multiply (magnification of objective lens)
