A pyramid of energy or pyramid of productivity shows the production or turnover (the rate at which energy or mass is transferred from one trophic level to the next) of biomass at each trophic level. Instead of showing a single snapshot in time, productivity pyramids show the flow of energy through the food chain. Typical units are grams per ...
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]
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 ...
The figure approximates the fraction of energy available after each stage of energy loss in a typical ecosystem, although these fractions vary greatly from ecosystem to ecosystem and from trophic level to trophic level. The loss of energy by a factor of one half from each of the steps of non-predatory death, defecation, and respiration is ...

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 ...
