In a food chain that undergoes biomagnification of a pesticide, which organism can expected to have the highest pesticide concentration?

Question

Quizplus · Accepted Answer

Carnivorous fish are at the top of the food chain and consume herbivorous fish that have already accumulated the pesticide from consuming contaminated zooplankton. Therefore, biomagnification causes the pesticide concentration to increase significantly in carnivorous fish, making them the organism with the highest pesticide concentration. Algae and zooplankton are lower in the food chain and are not expected to accumulate high levels of the pesticide.
