The type of organism likely to suffer the most from the effects of biological magnification is a top predator, such as large fish, Birds of Prey, or mammals. These organisms accumulate higher concentrations of toxic substances, like heavy metals or persistent organic pollutants, as they consume smaller prey that have already accumulated these toxins. The higher up the food chain an organism is, the more pronounced the effects of biological magnification become, leading to health issues and potential population declines.
