  2. Nutrient cycle - Wikipedia

    en.wikipedia.org/wiki/Nutrient_cycle

    There is much overlap between the terms for the biogeochemical cycle and nutrient cycle. Most textbooks integrate the two and seem to treat them as synonymous terms. [5] However, the terms often appear independently. The nutrient cycle is more often used in direct reference to the idea of an intra-system cycle, where an ecosystem functions as a ...

  3. 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 ...

  4. Food web - Wikipedia

    en.wikipedia.org/wiki/Food_web

    Food webs depict the pathways of mineral nutrient cycling as they flow through organisms. [6] [18] Most of the primary production in an ecosystem is not consumed, but is recycled by detritus back into useful nutrients. [54] Many of the Earth's microorganisms are involved in the formation of minerals in a process called biomineralization.

  5. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    Ecosystem respiration is the sum of respiration by all living organisms (plants, animals, and decomposers) in the ecosystem. [16] Net ecosystem production is the difference between gross primary production (GPP) and ecosystem respiration. [ 17 ]

  6. Ecology - Wikipedia

    en.wikipedia.org/wiki/Ecology

    Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production , nutrient cycling , and niche construction , regulate the flux of energy and matter through an environment.

  7. Biogeochemistry - Wikipedia

    en.wikipedia.org/wiki/Biogeochemistry

    Biogeochemistry is the scientific discipline that involves the study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environment (including the biosphere, the cryosphere, the hydrosphere, the pedosphere, the atmosphere, and the lithosphere).

  8. Ecosystem service - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_service

    Nutrient cycling is the movement of nutrients through an ecosystem by biotic and abiotic processes. [26] The ocean is a vast storage pool for these nutrients, such as carbon, nitrogen and phosphorus. The nutrients are absorbed by the basic organisms of the marine food web and are thus transferred from one organism to the other and from one ...

  9. Soil food web - Wikipedia

    en.wikipedia.org/wiki/Soil_food_web

    The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals. Food webs describe the transfer of energy between species in an ecosystem.
