  2. Abiotic component - Wikipedia

    en.wikipedia.org/wiki/Abiotic_component

    Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms.

  3. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    Ecosystem classifications are specific kinds of ecological classifications that consider all four elements of the definition of ecosystems: a biotic component, an abiotic complex, the interactions between and within them, and the physical space they occupy. Biotic factors of the ecosystem are living things; such as plants, animals, and bacteria ...

  4. Ecosystem ecology - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_ecology

    Ecosystem services are ecologically mediated functional processes essential to sustaining healthy human societies. [6] Water provision and filtration, production of biomass in forestry, agriculture, and fisheries, and removal of greenhouse gases such as carbon dioxide (CO 2) from the atmosphere are examples of ecosystem services essential to public health and economic opportunity.

  5. Outline of ecology - Wikipedia

    en.wikipedia.org/wiki/Outline_of_ecology

    Ecosystem – Community of living organisms together with the nonliving components of their environment, or Biome – Biogeographical unit with a particular biological community Community (ecology) – Associated populations of species in a given area, or Biocoenosis – Interacting organisms living together in a habitat

  6. Ecology - Wikipedia

    en.wikipedia.org/wiki/Ecology

    Ecosystems may be habitats within biomes that form an integrated whole and a dynamically responsive system having both physical and biological complexes. Ecosystem ecology is the science of determining the fluxes of materials (e.g. carbon, phosphorus) between different pools (e.g., tree biomass, soil organic material).

  7. Natural environment - Wikipedia

    en.wikipedia.org/wiki/Natural_environment

    Eugene Odum, one of the founders of the science of ecology, stated: "Any unit that includes all of the organisms (i.e.: the "community") in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (i.e.: exchange of materials between living ...

  8. Portal:Ecology - Wikipedia

    en.wikipedia.org/wiki/Portal:Ecology

    Ecosystems have biophysical feedback mechanisms that moderate processes acting on living and abiotic components of the planet. Ecosystems sustain life-supporting functions and provide ecosystem services like biomass production (food, fuel, fiber, and medicine), the regulation of climate, global biogeochemical cycles, water filtration, soil ...

  9. Community (ecology) - Wikipedia

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

    An ecosystem engineer is a species that maintains, modifies and creates aspects of a community. They cause physical changes to the habitat and alter the resources available to the other organisms present. [22] Dam building beavers are ecological engineers. Through the cutting of trees to form dams they alter the flow of water in a community.
