  2. Trophic level - Wikipedia

    en.wikipedia.org/wiki/Trophic_level

    The energy transferred between levels can also be thought of as approximating to a transfer in biomass, so energy pyramids can also be viewed as biomass pyramids, picturing the amount of biomass that results at higher levels from biomass consumed at lower levels. However, when primary producers grow rapidly and are consumed rapidly, the biomass ...

  3. Ecological pyramid - Wikipedia

    en.wikipedia.org/wiki/Ecological_pyramid

    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 ...

  4. Energy flow (ecology) - Wikipedia

    en.wikipedia.org/wiki/Energy_flow_(ecology)

    [2] [3] Each of the levels within the food chain is a trophic level. [1] In order to more efficiently show the quantity of organisms at each trophic level, these food chains are then organized into trophic pyramids. [1] The arrows in the food chain show that the energy flow is unidirectional, with the head of an arrow indicating the direction ...

  5. Food web - Wikipedia

    en.wikipedia.org/wiki/Food_web

    Ecological trophic pyramids are typically one of three kinds: 1) pyramid of numbers, 2) pyramid of biomass, or 3) pyramid of energy. [6] Food webs have trophic levels and positions. Basal species, such as plants, form the first level and are the resource-limited species that feed on no other living creature in the web.

  6. Biomass (ecology) - Wikipedia

    en.wikipedia.org/wiki/Biomass_(ecology)

    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 ...

    English: This is a pyramid-shaped diagram, showing how energy is transferred between trophic layers in an ecosystem, as well as what happens to other energy that is not transferred to the next layer. It was created by me utilizing the digital drawing tool Clip Studio Paint.

    In 2023, the first full year of the credit, EV sales jumped 46% year over year to 1.19 million, compared to 813,000 in 2022, according to Cox’s Kelly Blue Book.

  9. Ecological efficiency - Wikipedia

    en.wikipedia.org/wiki/Ecological_efficiency

    Thus, the net production at one trophic level is / / / = / or approximately ten percent that of the trophic level before it. For example, assume 500 units of energy are produced by trophic level 1. One half of that is lost to non-predatory death, while the other half (250 units) is ingested by trophic level 2.
