Question

Which is an example of true pyramid in an ecosystem?

• A. Pyramid of biomass
• B. Pyramid of number
• C. Pyramid of energy
• D. None of the above

Answer 1

The correct option is C Pyramid of energy

An ecological pyramid is the graphic representation of an ecological parameter like a number, biomass and energy, sequence wise in various trophic levels of a food chain, with producers at the base, herbivores in the middle and carnivores at top tiers.

Pyramid of energy gives a graphic representation of the amount of energy trapped by different trophic levels per unit area. It is always upright because during transfer of energy from one trophic level to the next a lot of wastage occurs. Because pyramid of energy is always upright it is called as a true pyramid in an ecosystem. Thus, the correct answer is option C.
