Question

In grassland ecosystem, the pyramid of biomass is

• A. upright
• B. inverted
• C. spindle shaped
• D. none of these

Answer 1

The correct option is A

upright

In terrestrial ecosystems like grasslands, the biomass generally decreases at each higher trophic level from plants via herbivores to carnivores. This is evident from the fact that the terrestrial producers’ viz. grasses, trees and shrubs have a much higher biomass than the animals that consume them, such as deer, zebras and insects. The level with the least biomass is the highest predators in the food chain, that consists of carnivores. Thus, in terrestrial ecosystems, the pyramid of biomass is upright.
