=== Detrital web ===

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.<ref>{{cite book | last1= Gönenç| first1= I.

Mushrooms produced by decomposers in the detrital web become a food source for deer, squirrels, and mice in the grazing web. [[Earthworm]]s eaten by robins are detritivores consuming decaying leaves.<ref>{{cite book | author= Gil Nonato C. Santos|author2=Alfonso C. Danac |author3=Jorge P.

"Detritus can be broadly defined as any form of non-living organic matter, including different types of plant tissue (e.g. [[leaf litter]], dead wood, aquatic macrophytes, algae), animal tissue (carrion), dead microbes, faeces (manure, dung, faecal pellets, guano, frass), as well as products secreted, excreted or exuded from organisms (e.g. extra-cellular polymers, nectar, root exudates and [[leachate]]s, dissolved organic matter, extra-cellular matrix, mucilage). The relative importance of these forms of detritus, in terms of origin, size and chemical composition, varies across ecosystems."<ref name="Moore04" />{{rp|585}}
