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 ...
Decomposers and detritivores complete this process, by consuming the remains left by scavengers. Scavengers aid in overcoming fluctuations of food resources in the environment. [ 3 ] The process and rate of scavenging is affected by both biotic and abiotic factors, such as carcass size, habitat, temperature, and seasons.
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.
"Detritivore" describes behavior and physiology, while "decomposer" describes an ecosystem role. Therefore, an organism can be both a detritivore and a decomposer. While there are also purely physical processes, like weathering and ultraviolet light , that contribute to decomposition, "decomposer" refers only to living organisms that contribute ...

What is left behind by the detritivores is then further broken down and recycled by decomposers, such as bacteria and fungi. This detritus cycle plays a large part in the so-called purification process, whereby organic materials carried in by rivers is broken down and disappears, and an extremely important part in the breeding and growth of ...
Beetle genera were mainly saprophages (detritivores) in the Permian and Triassic. During the Jurassic, herbivorous and then carnivorous genera became more common. In the Cenozoic, genera at all three trophic levels became far more numerous.
