Biomass pyramid is reversed in which of the following ecosystem ? 

The correct answer is Ponds.

Key Points

• In an aquatic ecosystem such as ponds, the biomass pyramid is often inverted.
• This means that the biomass of primary producers (phytoplankton) is less than the biomass of primary consumers (zooplankton).
• Phytoplankton have a high turnover rate which means they are quickly consumed by zooplankton, leading to a lower biomass at any given time.
• Zooplankton have a longer lifespan and a higher biomass as they feed on phytoplankton.
• This inversion is unique to certain aquatic ecosystems and does not typically occur in terrestrial ecosystems.

 Additional Information

• Drylands
  • In drylands ecosystems, the biomass pyramid is typically upright.
  • This is due to the low productivity and slow turnover rates of vegetation.
  • Primary producers such as grasses and shrubs have a higher biomass compared to primary consumers.
• Forest
  • In forest ecosystems, the biomass pyramid is generally upright.
  • Forests have a large biomass of primary producers (trees) compared to primary consumers.
  • Trees have a long lifespan and accumulate significant biomass over time.
• Grassland
  • In grassland ecosystems, the biomass pyramid is also upright.
  • Primary producers like grasses have a higher biomass than primary consumers.
  • Grasslands support a high number of herbivores, but their biomass is less compared to the vast expanse of grasses.
