Which trophic level has the least bioaccumulation?

Question

Quizplus · Accepted Answer

Primary producers (such as plants) generally have the least bioaccumulation because they are at the lowest trophic level and are the starting point of the food web. They may still accumulate some toxins or pollutants from the environment, but these are generally diluted across many individuals rather than being concentrated in a single organism. Heterotrophs, primary consumers, secondary consumers, and tertiary consumers are all higher up the trophic levels and are more likely to accumulate higher levels of toxins through biomagnification.
