An ecological pyramid (or trophic pyramid) is a graphical representation designed to show the biomass Biomass, in ecology, is the mass of living biological organisms in a given area or ecosystem at a given time. Biomass can refer to species biomass, which is the mass of one or more species, or to community biomass, which is the mass of all species in the community. It can include microorganisms, plants or animals. The mass can be expressed as the or productivity Primary production is the production of organic compounds from atmospheric or aquatic carbon dioxide, principally through the process of photosynthesis, with chemosynthesis being much less important. All life on earth is directly or indirectly reliant on primary production. The organisms responsible for primary production are known as primary at each trophic level In ecology, trophic dynamics is the system of trophic levels , which describe the position that an organism occupies in a food chain — what an organism eats, and what eats the organism in a given ecosystem An ecosystem is a natural unit consisting of all plants, animals and micro-organisms in an area functioning together with all of the physical (abiotic) factors of the environment. An ecosystem is a unit of interdependent organisms which share the same habitat. Ecosystems usually form a number of food webs which show the interdependence of the. Biomass Biomass, in ecology, is the mass of living biological organisms in a given area or ecosystem at a given time. Biomass can refer to species biomass, which is the mass of one or more species, or to community biomass, which is the mass of all species in the community. It can include microorganisms, plants or animals. The mass can be expressed as the pyramids show the abundance or biomass of organisms at each trophic level, while productivity Primary production is the production of organic compounds from atmospheric or aquatic carbon dioxide, principally through the process of photosynthesis, with chemosynthesis being much less important. All life on earth is directly or indirectly reliant on primary production. The organisms responsible for primary production are known as primary pyramids show the production or turnover in biomass. Ecological pyramids begin with producers An autotroph [α] is an organism that produces complex organic compounds from simple inorganic molecules using energy from light or inorganic chemical reactions on the bottom and proceed through the various trophic levels, the highest of which is on top. In Ecological Pyramid the arrangements from below is producers then primary consumers then secondary consumers and on the top is decomposers.
