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.
All species in the genus Xenophora are detritivores (and heterotrophic, meaning they do not produce their own food). Detritivores feed on dead organic material, most commonly plant detritus. All detritivores are important in their ecosystems because they cycle nutrients in the carbon, nitrogen, and phosphorus cycle.
Subimago and adult mayflies do not have functioning mouthparts and do not eat; the nymphs are mainly detritivores, feeding on organic particles that are moved into their burrows by the current of water caused by their constantly beating gills. [3] In their nymphal state, they are preyed on by dragonfly nymphs which attack them in their burrows.
While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding behavior. [2] Scavengers play an important role in the ecosystem by consuming dead animal and plant material. Decomposers and detritivores complete this process, by consuming the remains left by scavengers.
The base or basal species in a food web are those species without prey and can include autotrophs or saprophytic detritivores (i.e., the community of decomposers in soil, biofilms, and periphyton). Feeding connections in the web are called trophic links. The number of trophic links per consumer is a measure of food web connectance.

The NCAA college football transfer portal will open on Dec. 9 and close on Dec. 28. Here is how it works.
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.
