Pyramid of Energy:
It is a graphical representation of the trophic structure and function of an ecosystem in terms of energy.
The pyramid of energy is always upright and can never be inverted, because when energy flows from a particular trophic level to the next higher trophic level, some energy is always lost as heat(thus at every step).
Each bar in the energy pyramid indicates the amount of energy present at each trophic level in given time or annually per unit area.
