Question

Which of the following factors can limit the number of trophic levels in a food web?

a. Too many small primary producers.
b. An inverted biomass pyramid.
c. A limited amount of sunlight.
d. An inverted energy pyramid.

Answer 1

Energy is a major factor that limits the number of trophic levels in a food chain.

Step-by-step explanation:

One major factor that limits the number of steps in a food chain is energy. Energy is lost at each trophic level and between trophic levels as heat and in the transfer to decomposers. Thus, after a limited number of trophic energy transfers, the amount of energy remaining in the food chain may not be great enough to support viable populations at higher trophic levels.
