The pyramid of energy is always upright....

The pyramid of energy is always upright.

Text Solution

Verified by Experts

(1) When the energy moves from one trophic level to the next one, there is loss of some energy in the form of heat.
(2) The energy therefore is always more on the lower trophic levels as compared to the higher trophic levels. Owing to the above reason the energy pyramid is always upright and never inverted.
