Question

imagine you are a marine scientist. which of the following organisms would you warn people to avoid eating due to the risk of high levels of toxins in their bodies as a result of biomagnification?
algae
phytoplankton
small fish
sharks

Explanation:

Biomagnification is the process by which the concentration of toxins increases as you move up the food - chain. Sharks are at a high trophic level in the marine food - chain. Algae and phytoplankton are at lower trophic levels and have lower toxin concentrations. Small fish are intermediate, but sharks, being apex predators, consume many smaller organisms over time, accumulating high levels of toxins.

Answer:

Sharks
