I want to ask this question from Causes of Water Pollution in portion Environmental Pollution of Energy Management

Answer 1

Correct choice is (a) Bioaccumulation

For explanation: The pesticides that eat by an organism keep on moving in an aquatic food chain. At each link in the food chain, these chemicals which do not pass out of the body get accumulated and cause bioaccumulation. High levels of pesticides such as DDT can cause thin shells in bird eggs.
