  2. Abiotic component - Wikipedia

    en.wikipedia.org/wiki/Abiotic_component

    Abiotic component. In biology and ecology, abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors and the phenomena associated with them underpin biology as a whole. They affect a plethora of species, in all forms of ...

  3. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    An ecosystem (or ecological system) consists of all the organisms and the abiotic pools (or physical environment) with which they interact. [3][4]: 5 [2]: 458 The biotic and abiotic componentsare linked together through nutrient cycles and energy flows. [5] "Ecosystem processes" are the transfers of energy and materials from one pool to another ...

  4. Ecosystem ecology - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_ecology

    Ecosystem ecology is the integrated study of living (biotic) and non-living (abiotic) 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. Ecosystem ecology examines physical and ...

  5. Abiotic stress - Wikipedia

    en.wikipedia.org/wiki/Abiotic_stress

    Abiotic stress. Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. [1] The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way. [2]

  6. Soil ecology - Wikipedia

    en.wikipedia.org/wiki/Soil_ecology

    Soil ecology is the study of the interactions among soil organisms, and between biotic and abiotic aspects of the soil environment. [1] It is particularly concerned with the cycling of nutrients, formation and stabilization of the pore structure, the spread and vitality of pathogens, and the biodiversity of this rich biological community.

  7. River ecosystem - Wikipedia

    en.wikipedia.org/wiki/River_ecosystem

    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 ...

  8. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule is ...

  9. Portal:Ecology - Wikipedia

    en.wikipedia.org/wiki/Portal:Ecology

    Ecology (from Ancient Greek οἶκος (oîkos) 'house' and -λογία (-logía) 'study of') is the natural science of the relationships among living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere levels. Ecology overlaps with the ...
