It is stated that the pyramid of energy is always upright. Justify
Answer»
The base of the pyramid of energy is occupied by producers, which have the maximum amount of energy.
When energy flow from one trophic level only 10% is transferred, there is always loss of some energy in the form of heat.
So, the amount of energy at higher trophic level will always be less than the lower trophic levels and pyramid of energy will be upright and be inverted.
