# Accumulation of non-biodegradable pesticides in the food chain in increasing amount at each higher trophic level is known as :**(a) **eutrophication ** (b)** pollution **(c) **biomagnification ** (d)** accumulation

Correct answer: (c) biomagnification

Explanation: The accumulation of non-biodegradable pesticides in the food chain in an increasing amount at each higher trophic level is known as biomagnification.
