Final answer:
Biomagnification is the process by which toxic substances become more concentrated as they move up the food chain.
Step-by-step explanation:
Biomagnification is the process by which the concentration of toxic substances increases as they move up the food chain. These substances can include heavy metals, pesticides, and industrial pollutants. As smaller organisms are eaten by larger ones, the toxins they have accumulated are transferred and become more concentrated at each trophic level. This can have detrimental effects on top predators such as birds and mammals.
