What is the meaning of Biomagnification

Dear Student
‚Äč
Biomagnification is the increase in the concentration of a substance with the increase in the trophic level. Lets take the example of DDT which have been applied on the farm lands. producers would accumulate certain amounts of DDT in them and then it would be passed on to the next trophic level. Concentration of DDT would increase with the trophic level. Producers having the minimum concentration while the tertiary consumers would have the highest concentration of DDT accumulation in them. This increase in concentration is termed biomagnification. Amount and concentration should not be confused with each other, amount might decrease in the trophic levels but the concentration increases.
