Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An ecological pyramid (or trophic pyramid) is a graphical representation designed to show the biomass or productivity at each trophic level in a given ecosystem. Biomass pyramids show the abundance or biomass of organisms at each trophic level, while productivity pyramids show the production or turnover in biomass. Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat herbivores, then carnivores that eat those carnivores, and so on). The highest level is the top of the food chain. In Ecological Pyramid the arrangements from below is producers then primary consumers then secondary consumers and on the top is decomposers.
