Hint: The amount of biomass in an ecosystem depends upon the number of organisms present at a particular trophic level. The amount of biomass at a trophic level decides the shape of the pyramid of biomass.
Complete step by step answer:
-The living and dead tissues in an ecosystem are known as biomass. The total biomass at each trophic level is represented by a graphical representation known as the pyramid of biomass.
-In an ecosystem, the biomass should decrease at a particular trophic level of the food chain. A pyramid of biomass, the base represents the producers or the first trophic level and the apex represents the tertiary or top consumer.
- The pyramid of biomass in a grassland ecosystem is always upright. This pyramid is upright because the number of secondary consumers or carnivores are less in number as compared to primary consumers or herbivores at the base of the pyramid.
-In this ecosystem, the biomass of secondary consumers is less as compared to others. Whereas the pyramid of biomass is inverted in the case of a pond ecosystem because the number of secondary consumers (large fishes) are more as compared to the primary consumers.
Hence, the correct option is (B) Upright.
Note:
Pyramid of biomass in a terrestrial or forest ecosystem is always upright because the amount of biomass decreases from herbivores to top carnivores.
