An organism, such as a bacterium, fungus, or insect, that feeds on dead plant or animal matter.

[German Detritivor : Latin dētrītus, something worn away, detritus (from past participle of dēterere, to lessen, wear away; see detriment) + Latin -vorus, eating, feeding on; see -vorous.]

Organisms were classified into functional groups based on ecological processes that involve soil fauna: soil engineers = ants, earthworms, Isoptera; detritivores = Dermaptera, Diplopoda, Coleoptera, Blattodea, Isopoda, Acari, Diptera; herbivores = Hemiptera, Orthoptera, Lepidoptera larvae, Mollusca, Phasmatodea; and predators = Araneae, Chilopoda, Opiliones, Pseudoscorpionida, Mantodea.
Ant nests are a habitat for a range of organisms living in association with their ant host, including many symbionts, detritivores and parasites (Holldobler & Wilson 1990).
Both species are primarily detritivores and algivores and are facultatively predaceous on small invertebrates (McKinley, 1973; Fisher et al.

The presence of allochthonous detritus sediments enhanced the abundance of detritivores like Oligochaetes (Manoharan et al, 2006)[34] which confirms the peak of annelid population during September at St I and II due to the ingression of allochthonous material into the wetland from catchment area during monsoon rains.
After each mass extinction event, new organisms take on the roles of carnivores, herbivores, detritivores and producers.
Among the best performing indicators for a set of north Pacific ecosystem models are biomass groups consisting of detritivores, flatfish, and zooplanktivorous fish, as well as some surprising compound metrics such as the ratio of forage fish to jellyfish biomass (Samhouri et al.
An abundance of oribatid mites is seen as an indication of high concentrations of camelid dung and thus greater food availability for these detritivores.
Collectively, they have an amazingly broad dietary repertoire, and include taxa that range from detritivores and other decomposers, microvores, fungivores to especially herbivores, but also are consumers of animals as predators, parasitoids and parasites and inhabit unusual habitats such as oil seeps, playa lake brines, and hot springs (Wheeler, 1990; Kristensen, 1999; Labandeira, 1999, 2002).
Dead insects are processed by a relatively simple food web, composed of detritivores (midges, mites, flesh flies, fungi and bacteria), bacterivores (protozoans and rotifers) and an omnivorous top predator, the larva of the pitcher plant mosquito, Wyeomyia smithii (Coquillet).
Coleopterans collected included detritivores, carrion feeders, predators, herbivores, and wood-boring species.
