This is an inverted pyramid:

• A. Pyramid of energy in a pond ecosystem
• B. Pyramid of numbers in a grassland
• C. Pyramid of biomass in a pond ecosystem
• D. Pyramid of biomass in a grassland

Answer 1

The correct option is C

Pyramid of biomass in a pond ecosystem

An inverted pyramid is formed when the number of individuals or biomass is minimum and increases at each trophic level. The pyramid of biomass in a pond ecosystem is an example of an inverted pyramid because the biomass of phytoplankton may be smaller than that of zooplankton.
