Why a lion would have the highest accumulation of the pesticide?

A lion would likely have the highest accumulation of pesticide due to biomagnification, a process where toxins become more concentrated at each level of the food chain. As lions are apex predators, they consume herbivores and carnivores that have already accumulated pesticides in their bodies from their diets. This means that the concentration of pesticides in lions is significantly higher than in the organisms lower in the food chain. Additionally, lions, being larger and having longer lifespans, have more time to accumulate these toxins.
