Saprotrophic nutrition / s æ p r ə ˈ t r ɒ f ɪ k,-p r oʊ-/ [1] or lysotrophic nutrition [2] [3] is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (e.g. Mucor) and with soil bacteria.
Saprotrophic bacteria are bacteria that are typically soil-dwelling and utilize saprotrophic nutrition as their primary energy source. They are often associated with soil fungi that also use saprotrophic nutrition and both are classified as saprotrophs. [1] A saprotroph is a type of decomposer that feeds exclusively on dead and decaying plant ...
[1] [2] This process is called saprotrophic nutrition. Fungi are examples of saprobiontic organisms, which are a type of decomposer. [citation needed] Saprobiontic organisms feed off dead and/or decaying biological materials.
The larger snail is L. stagnalis with saprobic value 2.0; the smaller one is possibly a Physa fontinalis with a value of 2.4.. The saprobic system is a tool to measure water quality, and specifically it deals with the capacity of a water body to self-regulate and degrade organic matter.
Organotrophs use organic compounds as electron/hydrogen donors. Lithotrophs use inorganic compounds as electron/hydrogen donors.. The electrons or hydrogen atoms from reducing equivalents (electron donors) are needed by both phototrophs and chemotrophs in reduction-oxidation reactions that transfer energy in the anabolic processes of ATP synthesis (in heterotrophs) or biosynthesis (in autotrophs).
Fungi are the primary decomposers in most environments, illustrated here Mycena interrupta.. Saprophages are organisms that obtain nutrients by consuming decomposing dead plant or animal biomass. [1]

Mycoplankton, like all fungi, play an essential roll in the degradation of detritus and organic matter from plants, as well as other larger organisms. [14] [15] By working with other microbial communities, mycoplankton efficiently convert particulate organic matter to dissolved organic matter as part of biogeochemical cycling. [12]
