Suppose that the concentration of DDT in a lake is 0.0000003 ppm (parts per million) and the concentration of DDT in the tissues of an osprey (a fish-eating bird) is 25 ppm. This is an example of ______________.

Question

Quizplus · Accepted Answer

Biomagnification is the process by which the concentration of a particular substance increases as it moves up the food chain. In this example, the DDT concentration in the lake is low, but it is getting magnified as it moves up the food chain, ultimately accumulating in the tissues of an osprey at a much higher concentration. Bioremediation refers to the use of living organisms to clean up contaminated environments, which is not applicable in this scenario. Bioreduction and biodegradation are processes that break down contaminants, which are also not applicable in this scenario. Biotruncation is not a recognized term in environmental science.
