Energy pyramids are necessarily upright in healthy ecosystems, that is, there must always be more energy available at a given level of the pyramid to support the energy and biomass requirement of the next trophic level. An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical ...
A food pyramid and a corresponding food web, demonstrating some of the simpler patterns in a food web A graphic representation of energy transfer between trophic layers in an ecosystem. Energy flow is the flow of energy through living things within an ecosystem. [1]
The energy converted through photosynthesis is carried through the trophic levels of an ecosystem as organisms consume members of lower trophic levels. Primary production can be broken down into gross and net primary production. Gross primary production is a measure of the energy that a photoautotroph harvests from the sun.
An energy pyramid illustrates how much energy is needed as it flows upward to support the next trophic level. Only about 10% of the energy transferred between each trophic level is converted to biomass. In general, each trophic level relates to the one below it by absorbing some of the energy it consumes, and in this way can be regarded as ...
A four level trophic pyramid sitting on a layer of soil and its community of decomposers. A three layer trophic pyramid linked to the biomass and energy flow concepts. In a pyramid of numbers, the number of consumers at each level decreases significantly, so that a single top consumer , (e.g., a polar bear or a human ), will be supported by a ...

Ecological trophic pyramids are typically one of three kinds: 1) pyramid of numbers, 2) pyramid of biomass, or 3) pyramid of energy. [5]: 598 A trophic level (from Greek troph, τροφή, trophē, meaning "food" or "feeding") is "a group of organisms acquiring a considerable majority of its energy from the lower adjacent level (according to ...
The pyramid then proceeds through the various trophic levels to the apex predators at the top. When energy is transferred from one trophic level to the next, typically only ten percent is used to build new biomass. The remaining ninety percent goes to metabolic processes or is dissipated as heat. This energy loss means that productivity ...
