Question

Quizplus · Accepted Answer

Toxic chemicals, also known as bioaccumulative substances, tend to accumulate and become more concentrated as they move up the food chain. This is because each level of the food chain consumes organisms from the level below, resulting in an accumulation of toxins in the tissues of the top predators, such as apex predators like eagles and polar bears. These top predators have a higher concentration of toxins than lower level organisms, which makes them more vulnerable to health problems and population decline. Therefore, the highest level of the food chain, which is usually occupied by top carnivores, tends to have the highest accumulation of toxic chemicals.
