Explanation:

Biomagnification is the process where toxins accumulate in organisms and increase up trophic levels. In a typical food chain, there are usually four trophic levels (producer, primary consumer, secondary consumer, tertiary consumer). Parts per million (ppm) measures toxin levels. Producers have lower toxin levels compared to higher - level consumers.

Answer:

When toxins accumulate in living organisms and move up trophic levels within a food chain, it is called biomagnification. The example shown here represents four trophic levels. Each measurement of parts per million (ppm) represents the level of toxin within the living organism in the food chain. The producer is represented with a toxin level of 0.04 ppm. The tertiary consumer has a toxin level of 25 ppm.
