Explanation:
Detailed explanation-1: -Where plants are the producers, mice are the primary consumer, snake and hawks are the secondary and tertiary consumers respectively. If any harmful chemical or toxin is consumed by the organism and it enters the food chain then it is passed on from one trophic level to the other. This is known as biomagnification.
Detailed explanation-2: -Bioaccumulation is the process by which toxins enter the food web by building up in individual organisms, while biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web.
