The pyramid of biomass in a grassland ecosystem is:

A grassland ecosystem typically exhibits an upright pyramid of biomass and numbers. A biomass pyramid graphically represents the amount of biomass present at each trophic level within an ecosystem. Similarly, a pyramid of numbers illustrates the quantity of organisms at each level of the food chain. In grassland ecosystems, the biomass decreases as you move up the trophic levels, with producers (grasses and plants) forming the broad base and top predators forming the narrow apex, creating the characteristic upright pyramid structure.
