Which kind of pyramid will be obtained if a small standing crop of lower trophic levels supports large standing crop of higher trophic levels?
Options
- AInverted pyramid of number
- BUpright pyramid of number
- CInverted pyramid of biomass
- DUpright pyramid of biomass
Correct answer
C. Inverted pyramid of biomass
Step-by-step solution
Each trophic level has a certain mass of living material at a particular time called the standing crop. The standing crop is measured as the mass of living organisms (biomass) or the number in a unit area. When the lower levels have lower standing crop than the higher level, the pyramid will be inverted, as in the case of the pyramid of biomass in an aquatic ecosystem.
