Ecological pyramids are graphical representations of trophic structure in which the first or producer level forms the base and successive levels the tiers which make up the apex. The numbers and biomass pyramids may be partly inverted, but not so the energy pyramid.
Ecological pyramids are quantitative ways of representing relationships between organisms in an ecosystem, built up from bars stacked one above another.
It is standard practice to place producers at the bottom of the pyramid, with primary consumers, secondary consumers, tertiary consumers etc above them.
