Why the pyramid of energy is always upright? Explain.
Advertisements
उत्तर
The pyramid of energy represents the total amount of energy consumed by each trophic level in a given food chain. An energy pyramid is always upright because the total amount of energy available for utilization in the layers above is less than the energy available in the lower levels. This happens because according to the 10% law of energy transfer, only 10% of the total energy is transferred from one trophic level to another.
