Which of the groups of organisms in the food web would most likely have accumulated the largest concentration of long lasting chemical pollutants in their bodies

The question is incomplete, the complete question is shown in the image attached

F

Explanation:

The image shows a food web. A food web shows all the possible feeding relationships in an ecosystem.

We have to know that the concentration of chemical pollutants increases in organisms as you move up the food web. Higher level organisms tend to accumulate a greater concentration of chemical pollutants than the organisms that are lower in the food web.

Thus, the organism which appears at the highest level of the food web shown in the image will most likely have accumulated the largest concentration of long lasting chemical pollutants in their bodies.
