Why the pyramid of energy is always upright? Explain.

• The energy pyramid shows the total amount of energy present at each trophic level in a given food chain.

• Pyramid of energy can never be inverted, is always upright because some energy is always lost as heat at each step when energy flows from a particular trophic level to the next trophic level.

• Energy at a lower trophic level is always morethan at a higher level.

• Transfer of energy follows 10 % law of energy transfer in which only 10 % of the energy is transferred to each trophic level from the lower trophic level and the amount of energy decreases at each successive trophic level.

• For their energy demands, organisms at each trophic level depend on those at the lower trophic level.
