Steep vertical gradient is nothing but an upright pyramid. And upright pyramid is always the pyramid of energy.
  • The ecological pyramid is always upright because the distribution of energy and biomass is always reducing as the trophic level becomes higher (from primary producer to tertiary consumer).
  • 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 10% law of energy transfer. Only 10% of the total energy is transferred from one trophic level to another.
  • Some energy is always lost as heat at each step. Finally it is lost to atmosphere and never goes back to Sun.
  • As the amount of energy decreases at each trophic level, the pyramid of energy is always upright
