Which statement best explains why persistent, fat-solublechemicals such as methylmercury accumulate in the highesttrophic levels?a. Animals at the highest trophic levels eat the lowest-quality food.b. The amount of biomass increases in each trophic level, and largeorganisms accumulate the most methylmercury.c. Large organisms are often herbivores, so they would consumemethylmercury directly.d. Methylmercury does not leave an animal’s body; each predatortherefore consumes the mercury contained in many prey.
