Final answer:
Biomagnification is the accumulation of toxins in the tissues of top predators. It occurs as smaller organisms at lower trophic levels accumulate toxins from their food and larger predators consume them.
Step-by-step explanation:
The accumulation of toxins in the tissues of top predators is called biomagnification. Biomagnification is the process by which certain toxins, such as heavy metals or pesticides, become more concentrated as they move up the food chain. In this process, smaller organisms at lower trophic levels accumulate toxins from their food, and as larger predators consume them, the toxins become more concentrated in their tissues.
