  2. 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.

  3. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    An ecosystem (or ecological system) is a system formed by organisms in interaction with their environment. [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors.

  4. Lake ecosystem - Wikipedia

    en.wikipedia.org/wiki/Lake_ecosystem

    Temperature is an important abiotic factor in lentic ecosystems because most of the biota are poikilothermic, where internal body temperatures are defined by the surrounding system. Water can be heated or cooled through radiation at the surface and conduction to or from the air and surrounding substrate. [ 6 ]

  5. Aquatic ecosystem - Wikipedia

    en.wikipedia.org/wiki/Aquatic_ecosystem

    An ecosystem is composed of biotic communities that are structured by biological interactions and abiotic environmental factors. Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow.

    English: Diagram of a tree, bee, and a bacterium that are living factors of biotic components found in an ecosystem that are influenced by abiotic componets (non-living factors). Date 25 May 2018

  7. Desert ecology - Wikipedia

    en.wikipedia.org/wiki/Desert_ecology

    Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however ...

  8. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, lithosphere and hydrosphere. For example, in the carbon cycle, atmospheric carbon dioxide is absorbed by plants through photosynthesis , which converts it into organic compounds that are used by organisms for energy and growth.

  9. Abiotic component - Wikipedia

    en.wikipedia.org/wiki/Abiotic_component

    Humans can make or change abiotic factors in a species' environment. For instance, fertilizers can affect a snail's habitat, or the greenhouse gases which humans utilize can change marine pH levels. Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and ...
