This behavior is a learned behavior which the chimpanzee learns as they grow up, observing the patterns that their parents do. This is also a matter of socialization, the process of passing over advantageous traits to their offspring in order to acquire food strategically. </span>
Pesticides may end up in water sources (such as rivers and the sea), as a consequence they end up in the food chain. Not only this, human water systems could be affected, resulting in humans ingesting these pesticides.
Pesticide presence increases as you go up the food chain because more food will be consumed (e.g: The larger fish may eat several small fish who are contaminated with the pesticide).
Example:
Algae (absorbs pesticide)—> small fish —> Larger fish —> Human
