  2. Decomposer - Wikipedia

    en.wikipedia.org/wiki/Decomposer

    The primary decomposer of litter in many ecosystems is fungi. [11] [12] Unlike bacteria, which are unicellular organisms and are decomposers as well, most saprotrophic fungi grow as a branching network of hyphae. Bacteria are restricted to growing and feeding on the exposed surfaces of organic matter, but fungi can use their hyphae to penetrate ...

  3. Decomposition - Wikipedia

    en.wikipedia.org/wiki/Decomposition

    Decomposition of plant matter occurs in many stages. It begins with leaching by water; the most easily lost and soluble carbon compounds are liberated in this process. [50] Another early process is physical breakup or fragmentation of the plant material into smaller pieces, providing greater surface area for colonization and attack by decomposers.

  4. Detritus - Wikipedia

    en.wikipedia.org/wiki/Detritus

    In water ecosystems, relatively little waste collects on the water bed, and so the progress of decomposition in water takes a more important role. Investigating the level of inorganic salts in sea ecosystems shows that unless there is an especially large supply, the quantity increases from winter to spring—but is normally extremely low in summer.

  5. Marine prokaryotes - Wikipedia

    en.wikipedia.org/wiki/Marine_prokaryotes

    Prokaryotes play important roles in ecosystems as decomposers recycling nutrients. Some prokaryotes are pathogenic , causing disease and even death in plants and animals. [ 5 ] Marine prokaryotes are responsible for significant levels of the photosynthesis that occurs in the ocean, as well as significant cycling of carbon and other nutrients .

  6. Detritivore - Wikipedia

    en.wikipedia.org/wiki/Detritivore

    The terms detritivore and decomposer are often used interchangeably, but they describe different organisms. Detritivores are usually arthropods and help in the process of remineralization. Detritivores perform the first stage of remineralization, by fragmenting the dead plant matter, allowing decomposers to perform the second stage of ...

  7. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.

  8. Plant litter - Wikipedia

    en.wikipedia.org/wiki/Plant_litter

    The consumption of the litterfall by decomposers results in the breakdown of simple carbon compounds into carbon dioxide (CO 2) and water (H 2 O), and releases inorganic ions (like nitrogen and phosphorus) into the soil where the surrounding plants can then reabsorb the nutrients that were shed as litterfall. In this way, litterfall becomes an ...

  9. Microfauna - Wikipedia

    en.wikipedia.org/wiki/Microfauna

    They fill essential roles as decomposers and food sources for lower trophic levels, and are necessary to drive processes within larger organisms. Populations of microfauna can reach up to ~10 7 (~10,000,000) individuals per g −1 (0.1g, or 1/10th of a gram) and are very common in plant litter, surface soils, and water films. [3]
