  2. 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 ...

  3. Energy flow (ecology) - Wikipedia

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

    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 of energy flow; energy is lost as heat at each step along the way. [2] [3]

    A trophic pyramid (a) and a simplified community food web (b) illustrating ecological relations among creatures that are typical of a northern Boreal terrestrial ecosystem. The trophic pyramid roughly represents each level's biomass (usually measured as total dry weight). Plants generally have the greatest biomass.

  7. Ecological network - Wikipedia

    en.wikipedia.org/wiki/Ecological_network

    Explaining the observed high levels of complexity in ecosystems [1] has been one of the main challenges and motivations for ecological network analysis, since early theory predicted that complexity should lead to instability. [2] Connectance: the proportion of possible links between species that are realized (links/species 2). In food webs, the ...
