An ecological pyramid (also trophic pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem. Biomass is the amount of living or organic matter present in an organism.Biomass pyramids show how much biomass is present in the organisms at each trophic level, while productivity pyramids show the production or turnover in biomass.n energy pyramid is a presentation of the trophic levels in an ecosystem. Energy from the sun is transferred through the ecosystem by passing through various trophic levels. Roughly 10% of the energy is transferred from one trophic level to the next, thus preventing a large amounts of trophic levels.
1 Biomass-the total dry weight of the organisms in a trophic level. 2  Biomass Pyramid-a diagram showing the biomass at each trophic level of a food chain. Definition of Pyramid of numbers: A pyramid of numbers shows  graphically the population of each level in a food chain.   Definition of Pyramid of Biomass: Pyramid of Biomass represents the  total biomass at each trophic level.
