  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. 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]

  4. Environmental factor - Wikipedia

    en.wikipedia.org/wiki/Environmental_factor

    Environmental factor. An environmental factor, ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. [1] Abiotic factors include ambient temperature, amount of sunlight, air, soil, water and pH of the water soil in which an organism lives. Biotic factors would include the availability of food ...

  5. Natural stress - Wikipedia

    en.wikipedia.org/wiki/Natural_Stress

    Abiotic stress is a naturally occurring factor that cannot be controlled by humans. One example of two stressors that are complementary to each other is wind and drought. Drought dries out the soil and kills the plants that are growing in the soil. After this occurs, the soil is left barren and dry.

  6. 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 ...

  7. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    e. An ecosystem (or ecological system) is a system that environments and their organisms form through their interaction. [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which ...

  8. Aquatic ecosystem - Wikipedia

    en.wikipedia.org/wiki/Aquatic_ecosystem

    An aquatic ecosystem is an ecosystem found in and around a body of water, in contrast to land-based terrestrial ecosystems. Aquatic ecosystems contain communities of organisms — aquatic life —that are dependent on each other and on their environment. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. [1]

  9. Environmental gradient - Wikipedia

    en.wikipedia.org/wiki/Environmental_gradient

    Environmental gradient. An environmental gradient, or climate gradient, is a change in abiotic (non-living) factors through space (or time). Environmental gradients can be related to factors such as altitude, depth, temperature, soil humidity and precipitation. Often times, a multitude of biotic (living) factors are closely related to these ...
