Question
Chapter 19, Problem 9MCQ
Summary Introduction
Introduction:
Biomagnification is the process of accumulation of toxic chemical in the body of organism at highest trophic level. Toxic chemical do not excrete from the body and are not degraded in the nature. So, their accumulation inside the body is very harmful.

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.

The energy pyramid is a shape often used to describe and identify roles of organisms in an ecosystem. image Using the sections of the pyramid provided, which answer choice describes a relationship found in an ecosystem? A. II represents secondary consumer and III represents a tertiary consumer, which explains why the top of the pyramid is smaller than the base. B. IV represents producers and I represents primary consumers which explains why the base of the pyramid is the largest. C. IV represents the top predator and I represents the primary producers, which explains why the base of the pyramid is larger than the top. D. I represents a predator and II represents a prey which explains why the top of the pyramid is smaller than the base.arrow_forwardWhich statement about energy flow in ecosystems is accurate? A.Energy flow reaches an equilibrium within ecosystems such that every trophic level has the same amount of energy. B. Because forests have relatively few large trees which support numerous smaller organisms, they have less energy at the lowest trophic level than at higher trophic levels. C. Energy is recycled within ecosystems, moving from producers to consumers to decomposers and back to producers. D. Energy flows through ecosystems with some lost at every transition resulting in lower trophic levels always containing more energy than higher trophic levels. E. Aquatic ecosystems have more energy at higher trophic levels than at lower trophic levels, whereas terrestrial ecosystems have more energy at lower trophic levels.
