  2. Decomposer - Wikipedia

    en.wikipedia.org/wiki/Decomposer

    Decomposers are organisms that break down dead organisms and release the nutrients from the dead matter into the environment around them. Decomposition relies on chemical processes similar to digestion in animals; in fact, many sources use the words digestion and decomposition interchangeably. [ 1 ]

  3. Decomposition - Wikipedia

    en.wikipedia.org/wiki/Decomposition

    Prime decomposers are bacteria or fungi, though larger scavengers also play an important role in decomposition if the body is accessible to insects, mites and other animals. Additionally, [ 3 ] soil animals are considered key regulators of decomposition at local scales but their role at larger scales is unresolved.

  4. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    The cycles are interconnected and play important roles regulating climate, supporting the growth of plants, phytoplankton and other organisms, and maintaining the health of ecosystems generally. Human activities such as burning fossil fuels and using large amounts of fertilizer can disrupt cycles, contributing to climate change, pollution, and ...

  5. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    Other external factors that play an important role in ecosystem functioning include time and potential biota, the organisms that are present in a region and could potentially occupy a particular site. Ecosystems in similar environments that are located in different parts of the world can end up doing things very differently simply because they ...

  6. Detritivore - Wikipedia

    en.wikipedia.org/wiki/Detritivore

    Fungi, acting as decomposers, are important in today's terrestrial environment. During the Carboniferous period , fungi and bacteria had yet to evolve the capacity to digest lignin , and so large deposits of dead plant tissue accumulated during this period, later becoming the fossil fuels .

  7. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Water is the medium of the oceans, the medium which carries all the substances and elements involved in the marine biogeochemical cycles. Water as found in nature almost always includes dissolved substances, so water has been described as the "universal solvent" for its ability to dissolve so many substances.

  8. Consumer (food chain) - Wikipedia

    en.wikipedia.org/wiki/Consumer_(food_chain)

    A consumer in a food chain is a living creature that eats organisms from a different population. A consumer is a heterotroph and a producer is an autotroph.Like sea angels, they take in organic moles by consuming other organisms, so they are commonly called consumers.

  9. Microbiology of decomposition - Wikipedia

    en.wikipedia.org/wiki/Microbiology_of_decomposition

    Decomposing pig showing signs of bloat and discoloration, a result of microbial proliferation within the body.. Microbiology of decomposition is the study of all microorganisms involved in decomposition, the chemical and physical processes during which organic matter is broken down and reduced to its original elements.
