  Allochthonous may have some obscure usage related to rocks, but in ecology, allochthonous material is a major concept that underpins thinking about nutrient cycling and food web its most general definition, allochthonous material is something imported into an ecosystem from outside of it. Usually, ecologists are thinking about organic matter and the nutrients (C, N, and P) . In ecology, allochthonous material is something imported into an ecosystem from outside of it, and in streams in particular, allochthonous material includes leaves that fall or are washed into the water and branches and trees that topple into the stream. Allochthonous material can also include dissolved organic matter (DOM) carried into the. Autochthonous is an antonym of allochthonous. Allochthonous is an antonym of autochthonous.

Processing of allochthonous detritus in streams can be affected by other aspects of stream hydrology. Foremost among these is retentiveness, which determines where decomposition of allochthonous organic material actually takes place once it has entered the stream. Detritivores (also known as detrivores, detritophages, detritus feeders, or detritus eaters), are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as faeces). There are many kinds of invertebrates, vertebrates and plants that carry out doing so, all these detritivores contribute to decomposition and the nutrient cycles.
