Quizplus · Accepted Answer

Biomagnification occurs when a pollutant is taken up by an organism at a lower trophic level and becomes increasingly concentrated as it moves up the food chain. Grizzly bears are at the top of the food chain in British Columbia ecosystems and feed on salmon, which are known to accumulate high levels of POPs. Therefore, we would expect to find the highest concentrations of POPs in grizzly bears that eat salmon from the oceans. The other options are less likely to have high concentrations of POPs due to either dilution in large water bodies (water in oceans), a lack of biomagnification in the food chain (algae), or lower trophic level in food chains (salmon living in oceans).
