The movement of pesticides in a lake from aquatic insects to the bald eagle occurs in several steps. For example, first the insects are contaminated by pesticides in the lake. If a trout consumes these insects, the trout's flesh now has pesticides in it. When the bald eagle swoops down to catch and eat the trout, it ends up eating the pesticides as well.
