Fungi are the primary decomposers in most environments, illustrated here Mycena interrupta. Saprophages are organisms that obtain nutrients by consuming decomposing dead plant or animal biomass. [1] They are distinguished from detritivores in that saprophages are sessile consumers while detritivores are mobile.
All saprotrophic bacteria are unicellular prokaryotes, and reproduce asexually through binary fission. [2] Variation in the turnover times (the rate at which a nutrient is depleted and replaced in a particular nutrient pool) of the bacteria may be due in part to variation in environmental factors including temperature, soil moisture, soil pH, substrate type and concentration, plant genotype ...
Cellulose, a major portion of plant cells, and therefore a major constituent of decaying matter is broken down into glucose; These products are re-absorbed into the hypha through the cell wall by endocytosis and passed on throughout the mycelium complex. This facilitates the passage of such materials throughout the organism and allows for ...
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 ]
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.
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 ...

In a detrital web, plant and animal matter is broken down by decomposers, e.g., bacteria and fungi, and moves to detritivores and then carnivores. [69] There are often relationships between the detrital web and the grazing web. Mushrooms produced by decomposers in the detrital web become a food source for deer, squirrels, and mice in the ...
