Which organism shown in the food web on page 198 contains the most ddt?

To determine which organism in the food web contains the most DDT, you would typically look at the top predators in the web, as DDT biomagnifies up the food chain. Organisms such as Birds of Prey or large carnivores often accumulate the highest concentrations of DDT due to their position at the top of the trophic levels. Without the specific food web from page 198, it’s difficult to name the exact organism, but generally, these top predators would be the most affected.
