Detailed explanation-1: -An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.

Detailed explanation-2: -Pyramids of energy show the relative amount of energy available at each trophic level. A pyramid of biomass illustrates the relative amount of living organic matter at each trophic level.

Detailed explanation-3: -An ecological pyramid is a graphical representation designed to show either the number, biomass and energy at each trophic level.

Detailed explanation-4: -Trophic level is the relative position of an entity in the food chain. It forms the feeding positions in a food web or chain. All food webs and chains have at least two or three trophic levels. An ecological pyramid depicts how energy and biomass decrease from lower to higher trophic levels.

Detailed explanation-5: -An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.
