What is biological magnification ? Will the levels of this magnification be different at different levels of the ecosystem.

Explanation

Biological magnification is defined as the phenomena of accumulation or increases in the concentration of some toxic substanc at each trophic level. The levels of biomagnification will be different at diffrent trophic levels. . For example, in a pond of water, DDT was sprayed and the producers were found to have 0.004ppm concentration of DDT. Since many types of planktons are eaten by some fishes and clams, their body accumalates 0.23ppm of DDT. Sea gull that feeds on clams accumalates more DDT as one sea gull eats many clams. Hawk, the top carnivore, has the highest concentration of DDT.
