What kind of seafood would you expect to have the highest levels of mercury and why? kelp, because they use the sun to photosynthesize on the bottom trophic level. oysters, because they filter feed on plankton on a lower trophic level. small fish, because they eat plankton on a higher trophic level. sharks, because they feed on organisms on a higher trophic level.

Answer: Sharks, because they feed on organisms on a higher trophic level.

Explanation:

The concentration of any toxic compound increases in the tissue of the organism as we move at higher levels in the food chain and, this is known as biological magnification.Since the sharks feed on the higher trophic level organisms in the food chain, the concentration of mercury would be the greatest as compared to the other organisms given in the question.

D. Sharks, because they feed on organisms on a higher trophic level.
