in an energy pyramid large amount of the energy gets dissipated only 10% of the energy is transferred to other level. Trophic level tells the placement of organism in a energy pyramid.
If at any time the pyramid gets blocked:
The passing of biomass and energy gets break to each level.
The organism at the higher level will be scarce of resources as nutrition and energy for growth, multiplication and metabolism.
The organisms at the higher level will get die eventually and vanish from the earth as no reproduction.
The energy dissipated will be in large amount disturbing the ecological chain.
The imbalance in energy would cause warming up of the planet and variety in fauna would be limited.
