Answer 1

When DDT was sprayed it got into water and soil and was taken up by producers like algae and plants at the bottom of the food chain. Small animals and insects that ate those producers passed DDT to bigger animals, some of which were secondary consumers, and the top predators like bald eagles were tertiary consumers. Because of biomagnification, DDT built up to high levels in those tertiary consumers and caused eggshell thinning in bald eagles.
