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.

Why are decomposers usually absent from food webs?
A. Decomposers do not have a feeding relationship with other organisms
B. Decomposers can operate at several different trophic levels
C. Decomposers can produce their own food
D. Decomposers can only access energy from dead organisms
Which 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.
