  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/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 ...

  7. Natural environment - Wikipedia

    en.wikipedia.org/wiki/Natural_environment

    A more significant number or variety of species or biological diversity of an ecosystem may contribute to greater resilience of an ecosystem because there are more species present at a location to respond to change and thus "absorb" or reduce its effects. This reduces the effect before the ecosystem's structure changes to a different state.

  8. Ecology - Wikipedia

    en.wikipedia.org/wiki/Ecology

    Ecosystems, for example, contain abiotic resources and interacting life forms (i.e., individual organisms that aggregate into populations which aggregate into distinct ecological communities). Because ecosystems are dynamic and do not necessarily follow a linear successional route, changes might occur quickly or slowly over thousands of years ...

  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.
