  2. Energy flow (ecology) - Wikipedia

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

    Energy flow is the flow of energy through living things within an ecosystem. [1] All living organisms can be organized into producers and consumers , and those producers and consumers can further be organized into a food chain .

  3. Ecological efficiency - Wikipedia

    en.wikipedia.org/wiki/Ecological_efficiency

    The energy remaining after respiration is considered the net primary production. In general, gross production refers to the energy contained within an organism before respiration and net production the energy after respiration. The terms can be used to describe energy transfer in both autotrophs and heterotrophs.

  4. Ecological pyramid - Wikipedia

    en.wikipedia.org/wiki/Ecological_pyramid

    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 ...

  5. Ecosystem ecology - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_ecology

    Population, community, and physiological ecology provide many of the underlying biological mechanisms influencing ecosystems and the processes they maintain. Flowing of energy and cycling of matter at the ecosystem level are often examined in ecosystem ecology, but, as a whole, this science is defined more by subject matter than by scale.

  6. Food web - Wikipedia

    en.wikipedia.org/wiki/Food_web

    Energy flow diagram of a frog. The frog represents a node in an extended food web. The energy ingested is utilized for metabolic processes and transformed into biomass. The energy flow continues on its path if the frog is ingested by predators, parasites, or as a decaying carcass in soil. This energy flow diagram illustrates how energy is lost ...

  7. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    Raymond Lindeman took these ideas further to suggest that the flow of energy through a lake was the primary driver of the ecosystem. Hutchinson's students, brothers Howard T. Odum and Eugene P. Odum, further developed a "systems approach" to the study of ecosystems. This allowed them to study the flow of energy and material through ecological ...

  8. Ecological facilitation - Wikipedia

    en.wikipedia.org/wiki/Ecological_facilitation

    Ecological facilitation or probiosis describes species interactions that benefit at least one of the participants and cause harm to neither. [1] Facilitations can be categorized as mutualisms, in which both species benefit, or commensalisms, in which one species benefits and the other is unaffected.

  9. Energy flow - Wikipedia

    en.wikipedia.org/wiki/Energy_flow

    Energy flow may refer to: Energy transfer, the transfer of physical energy from one body or place to another; Energy flow (ecology), the flow of energy through a biological food chain; Energy (esotericism) flow, the movement of spiritual energy; Fluid dynamics, energy of a flowing fluid related to pressure "Energy Flow", a 1999 song by Ryuichi ...
