Final answer:
Biomagnification is the process of toxin concentration increasing with each link in the food chain or trophic level.
Step-by-step explanation:
Biomagnification is the process by which the concentration of a toxic substance increases with each successive link in the food chain or in each advancing trophic level. This means that organisms higher up in the food chain, such as predators, accumulate higher levels of the toxin in their bodies. The lower trophic levels absorb the toxin from their food, and as it moves up the food chain, the concentration increases.
