What type of consumer will eventually accumulate the most insecticide in its body?

Top predators in a food chain, such as Birds of Prey or large mammals, are likely to accumulate the most insecticide in their bodies due to a process known as biomagnification. As these animals consume prey that has already absorbed insecticides, the concentration of these harmful substances increases at each trophic level. Consequently, the higher up an animal is in the food chain, the greater the accumulation of toxins, leading to potentially harmful effects on their health.
