Answer 1

The organisms in the food web that would contain the lowest concentration of chemical pollutants per individual are producers such as phytoplankton.

In a food web, producers are at the base and generally accumulate fewer pollutants compared to higher trophic levels. This is because pollutants tend to concentrate as you move up the food chain, a phenomenon known as biomagnification. Thus, phytoplankton, being primary producers, would have lower concentrations of pollutants compared to consumers.
