Why do think predatory animals like owls are often threatened in habitats that have been exposed to those chemicals?
antiseptic1488 [7]

Answer:

At each higher level of consumption, the amount of toxin is magnified.

Explanation:

Those predators all eat smaller secondary consumers, and those secondary consumers eat the primary consumers, which a lot of the times are exposed to DDT. For example bugs are often the primary target for DDT, once those bugs are exposed to the DDT they carry it in/with them. When a fish eats the bug, that fish is now exposed to the DDT. When the fish is caught and eaten by an eagle that eagle and its young are now being exposed to DDT. The DDT might not effect the full grown eagle for its lifetime but it does effect its young.
