which organisms in the food web contain the lowest concentration of chemical pollutants per individual

Answer 1

Typically, organisms at the lowest trophic level or primary producers, such as plants or algae, have the lowest concentration of chemical pollutants per individual. This is because they are generally less exposed to pollutants compared to consumers at higher trophic levels. However, it is crucial to note that the concentration of pollutants can vary depending on various factors such as the specific pollutant, location, and ecosystem dynamics.
