Answer 1

Biomagnification is the process where toxic chemicals become more concentrated in animal tissues as it moves up the food chain.

Step-by-step explanation:

Biomagnification is the process by which toxic chemicals become more concentrated in animal tissues as it moves up the food chain. This happens because animals at higher trophic levels consume larger amounts of prey, thus accumulating higher levels of the toxic chemicals present in those prey. For example, if a primary consumer consumes plants that have been contaminated with pesticides, the toxic chemicals will accumulate in its body. When a secondary consumer then eats multiple primary consumers, the concentration of the toxic chemicals will be even higher in the secondary consumer. This process continues as you move up the food chain, leading to higher concentrations of toxic chemicals in top predators.
