Why do herbivores have more DDE inside of them than the producers?

Herbivores do not have more DDE inside of them than the producers. In fact, the concentration of DDE increases as it moves up the food chain. This is because DDE is a fat-soluble chemical, which means that it is stored in the body fat of organisms. As herbivores eat plants, they ingest a small amount of DDE. This DDE is then stored in their body fat. When carnivores eat herbivores, they ingest a larger amount of DDE, which is then stored in their body fat. This process of biomagnification results in higher concentrations of DDE in carnivores than in herbivores.
