Toxic burden of a large number of organisms at a lower trophic level is accumulated and concentrated by a predator at a higher trophic level.
Correct Answer
BiomagnificationExplanation
Biomagnification refers to the process where the concentration of toxic substances increases as they move up the food chain. In this case, the toxic burden of multiple organisms at a lower trophic level accumulates and becomes more concentrated in a predator at a higher trophic level. This occurs because predators consume a large number of prey organisms, each containing a certain amount of toxins. As these toxins are not easily metabolized or excreted, they become more concentrated in the predator's body over time. This phenomenon highlights the potential for environmental pollutants to have a greater impact on higher-level predators.Rate this question:
