The term "decomposer" refers to a role in an ecosystem, not to a particular class or type of organism, or even to a specific capacity of those organisms. [5] The definition of "decomposer" therefore centers on the outcome of the decomposition process, rather than the types of organisms performing it.
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.
Ecosystem ecology is philosophically and historically rooted in terrestrial ecology. The ecosystem concept has evolved rapidly during the last 100 years with important ideas developed by Frederic Clements, a botanist who argued for specific definitions of ecosystems and that physiological processes were responsible for their development and persistence.

Microbial life plays a primary role in regulating biogeochemical systems in virtually all environments, including some of the most extreme, from frozen environments and acidic lakes, to hydrothermal vents at the bottom of the deepest oceans, and some of the most familiar, such as the human small intestine, nose, and mouth.
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 ...
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 ...

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.
