Question

what is biomagnification? the complete elimination of a substance from the food chain the increase in substance concentration in organisms as it moves up the food chain the dilution of toxins in organisms as they move up the food chain the stagnation of a substance in a specific trophic level

Explanation:

Biomagnification is a process in which the concentration of a substance (often a toxin) increases as it moves up the food chain. For example, small organisms may take in a small amount of a toxin, and when they are eaten by larger organisms, the toxin gets concentrated because the larger organism eats many small ones. This is a key concept in environmental sciences as it can lead to high levels of toxins in top - level predators.

Answer:

the increase in substance concentration in organisms as it moves up the food chain
