Answer
This is called biomagnification.
Toxic chemicals accumulate in small organisms at the bottom of the food chain. As they get eaten by organisms which are above them in the food chain, these toxins become more concentrated. Killer whales, bein at the top of the food chain, accumulate the highest concentration of these toxins, which severely affects them. Hence, it affects the whole food chain of an ecosystem.
