In most ecosystems, the pyramid of ___________________ is always upright when there are more producers than primary consumers.

• A. Energy
• B. Number
• C. Biomass
• D. All of the above

Answer 1

Answer: (D)

In most ecosystems, all the pyramids, of number, of energy and biomass are upright, i.e., producers are more in number and biomass than the herbivores, and herbivores are more in number and biomass than the carnivores. Addionally, energy at a lower trophic level is always more than that at a higher level.
