Question

Quizplus · Accepted Answer

Sharks are apex predators and are at the top of the food chain, which means they consume smaller fish that may contain mercury. As a result, large predatory fish such as sharks have a higher likelihood of containing high levels of mercury. Sharks are apex predators in the food chain and have a longer lifespan, so they accumulate more mercury in their tissues over time. Therefore, they are most likely to contain high levels of mercury.
