Question

Based on your knowledge of bioaccumulation, which organism would you expect to contain the highest amount of PCBs?

1) Fish
2) Birds
3) Insects
4) Plants

Answer 1

Based on the information provided, birds would contain the highest amount of PCBs in an ecosystem.

Step-by-step explanation:

Based on the information provided, the organism that would be expected to contain the highest amount of PCBs is birds. PCBs, or polychlorinated biphenyls, have been found to bioaccumulate in aquatic ecosystems. In the food chain, PCB concentrations increase as they move up through the different trophic levels of fish species. Birds that consume these fish may have PCB levels at least one order of magnitude higher than those found in the lake fish.
