  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

    [3] [4]: 5 [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. [5] "Ecosystem processes" are the transfers of energy and materials from one pool to another. [2]: 458 Ecosystem processes are known to "take place at a wide range of scales". Therefore, the correct scale of study depends on the ...

  4. Ecosystem ecology - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_ecology

    Ecosystem ecology is the integrated study of living and non-living components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals , bedrock , soil , plants , and animals .

  5. River ecosystem - Wikipedia

    en.wikipedia.org/wiki/River_ecosystem

    This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.

  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. Lake ecosystem - Wikipedia

    en.wikipedia.org/wiki/Lake_ecosystem

    Lentic ecosystems can be compared with lotic ecosystems, which involve flowing terrestrial waters such as rivers and streams. Together, these two ecosystems are examples of freshwater ecosystems. Lentic systems are diverse, ranging from a small, temporary rainwater pool a few inches deep to Lake Baikal, which has a maximum depth of 1642 m. [2]

  8. Natural environment - Wikipedia

    en.wikipedia.org/wiki/Natural_environment

    An ecosystem (also called an environment) is a natural unit consisting of all plants, animals, and micro-organisms (biotic factors) in an area functioning together with all of the non-living physical factors of the environment. [34]

  9. 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
