Question

Which of the following pyramids always shows a steeper vertical gradient i.e., upright?

• A. Pyramid of number
• B. Pyramid of nutrients
• C. Pyramid of biomass
• D. Pyramid of energy

Answer 1

The correct option is D Pyramid of energy

An energy pyramid is a model that shows the flow of energy from one trophic level to the next in an ecosystem. Pyramid of energy is always upright because energy at a lower trophic level is always more than at a higher level. When energy flows from a particular trophic level to the next trophic level, some energy is always lost as heat at each step.
