Q. Which among the following ecosystems exhibit an inverted pyramid of biomass?- Grassland
- Pond
- Forest
Select the correct option from the codes given below:
Answer:
Only 2
Notes: In grassland and forest ecosystems, the pyramid of biomass is upright as the biomass decreases at higher trophic levels. In pond ecosystems, the pyramid of biomass is inverted because the producer level (phytoplankton) has less biomass than the primary consumers. Hence, only in ponds does an inverted pyramid of biomass occur.
