Detailed explanation-1: -As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller. While energy can not be created or destroyed is it released as heat within each level. Approximately only 10% of energy is passed from one level to the next.

Detailed explanation-2: -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-3: -In an ecological pyramid, the various trophic levels are primary producers (at the base), consumers (primary, secondary, tertiary, etc.), and predators (apex). There are essentially two major types of organisms based on their feeding mode.

Detailed explanation-4: -An ecological pyramid is a graphical representation designed to show either the number, biomass and energy at each trophic level.
