Question 8 (1 point)
The diagram is a pyramid of biomass for a meadow ecosystem. The triangular shape of the diagram is useful for explaining which relationship among the trophic levels in this ecosystem?
A triangle-shaped diagram shows meadow grasses at its wide base. Above it are a row of rabbits, mice, and grasshoppers. Above them are snakes. At the top of the triangle is a hawk or eagle.
a
The amount of available biomass is equal at all trophic levels in this ecosystem.
b
The amount of biomass decreases at each trophic level in this ecosystem.
c
Third-level consumers in this ecosystem have the greatest amount of biomass.
d
With each step to a higher trophic level in this ecosystem, the amount of biomass increases.

The triangular shape of the diagram indicates the distribution of biomass among different trophic levels in the ecosystem. In a typical biomass pyramid, the primary producers (like meadow grasses) at the base have the largest biomass, while the biomass decreases as you move up to the higher trophic levels (herbivores, then carnivores, and finally apex predators).
Thus, the correct answer is:
**b The amount of biomass decreases at each trophic level in this ecosystem.**
Thus, the correct answer is:
**b The amount of biomass decreases at each trophic level in this ecosystem.**
