In the 1940s, the chemical DDT was used as a pesticide to control mosquito populations in different areas of the world. The use of this chemical contributed to a decrease in eagle populations due to weak egg shells that broke or eggs that did not hatch. An example of an ecosystem that includes eagles is shown in the model.
Based on information in the model, how was DDT introduced into eagle populations?
DDT chemicals were taken in by the zooplankton, which were eaten by small fish, which were eaten by large fish, which were eaten by eagles.
