  2. Environmental degradation - Wikipedia

    en.wikipedia.org/wiki/Environmental_degradation

    With regard to the agriculture sector for example, The State of the World's Biodiversity for Food and Agriculture, published by the Food and Agriculture Organization of the United Nations in 2019, [18] states that "countries report that many species that contribute to vital ecosystem services, including pollinators, the natural enemies of pests ...

  3. Land degradation - Wikipedia

    en.wikipedia.org/wiki/Land_degradation

    As per the Millennium Ecosystem Assessment of 2005, land degradation is in defined as "the reduction or loss of the biological or economic productivity of drylands". [5] A similar definition states that land degradation is the "degradation, impoverishment and long-term loss of ecosystem services".

  4. Geochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Geochemical_cycle

    Some [who?] may use the terms biogeochemical cycle and geochemical cycle interchangeably because both cycles deal with Earth's reservoirs.However, a biogeochemical cycle refers to the chemical interactions in surface reservoirs such as the atmosphere, hydrosphere, lithosphere, and biosphere [citation needed] whereas a geochemical cycle refers to the chemical interactions that exist in crustal ...

  5. Biodegradation - Wikipedia

    en.wikipedia.org/wiki/Biodegradation

    For example, lactide-based plastics are inferior packaging properties in comparison to traditional materials. Oxo-biodegradation is defined by CEN (the European Standards Organisation) as "degradation resulting from oxidative and cell-mediated phenomena, either simultaneously or successively."

  6. Amphibolic - Wikipedia

    en.wikipedia.org/wiki/Amphibolic

    The citric acid cycle (Krebs cycle) is a good example of an amphibolic pathway because it functions in both the degradative (carbohydrate, protein, and fatty acid) and biosynthetic processes. [2] The citric acid cycle occurs on the cytosol of bacteria and within the mitochondria of eukaryotic cells.

  7. Metabolic pathway - Wikipedia

    en.wikipedia.org/wiki/Metabolic_pathway

    The degradative process of a catabolic pathway provides the energy required to conduct the biosynthesis of an anabolic pathway. [6] In addition to the two distinct metabolic pathways is the amphibolic pathway, which can be either catabolic or anabolic based on the need for or the availability of energy.

  8. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    Biogeochemical cycle – Chemical transfer pathway between Earth's biological and non-biological parts; Climate change mitigation – Actions to reduce net greenhouse gas emissions to limit climate change; Carbon dioxide in Earth's atmosphere – Atmospheric constituent and greenhouse gas; Carbon sequestration – Storing carbon in a carbon pool

  9. Landscape connectivity - Wikipedia

    en.wikipedia.org/wiki/Landscape_connectivity

    [9] Nine years later, Merriam and colleagues, revised the definition to "the degree to which the landscape impedes or facilitates movement among resource patches. [1] Although this definition has undoubtedly become the most accepted and cited meaning within the scientific literature, many authors have continued to create their own definitions.
