Pesticides can accumulate in bodies of water to levels that kill off zooplankton, the main source of food for young fish. [92] Pesticides can also kill off insects on which some fish feed, causing the fish to travel farther in search of food and exposing them to greater risk from predators. [90]

Biomagnification, also known as bioamplification or biological magnification, is the increase in concentration of a substance, e.g a pesticide, in the tissues of organisms at successively higher levels in a food chain. [1] This increase can occur as a result of: Persistence – where the substance cannot be broken down by environmental processes.
