Due to the limited vegetation available in the desert, desert detritivores adapted and evolved ways to feed in the extreme conditions of the desert. [3] Detritivore feeding behaviour is affected by rainfall; moist soil increases detritivore feeding and excretion. [7] Fungi, acting as decomposers, are important in today's terrestrial environment.
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.

They are typically detritivores, provisioning their nests with leaf litter (often moldy), but are occasionally coprophagous, similar to dung beetles. The eggs are laid in or upon the provision mass and buried, and the developing larvae feed upon the provisions. The burrows of some species can exceed 2 metres in depth.

Another more widely used method of feeding, which also incorporates filter feeding, is a system where an organism secretes mucus to catch the detritus in lumps, and then carries these to its mouth using an area of cilia. Many organisms, including sea slugs and serpent's starfish, scoop up the detritus which has settled on the water bed.
Specific feeding strategies and mechanisms are employed to match specific niches. [31] Herbivorous and detritivorous species fragment biological material present in soil and leaf litter, supporting decomposition and increasing the availability of nutrients for various species of microbes and fungi.

For example, a marine habitat with five trophic levels could be represented as follows: Herbivores (feed primarily on phytoplankton); Carnivores (feed primarily on other zooplankton/animals); Detritivores (feed primarily on dead organic matter/detritus; Omnivores (feed on a mixed diet of phyto- and zooplankton and detritus); and Mixotrophs ...
