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.
[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.
[citation needed] Typical saprophagic animals include sedentary polychaetes such as amphitrites (Amphitritinae, worms of the family Terebellidae) and other terebellids. The eating of wood, whether live or dead, is known as xylophagy. The activity of animals feeding only on dead wood is called sapro-xylophagy and those animals, sapro-xylophagous.
Heterotrophic nutrition means that fungi utilize extracellular sources of organic energy, organic material or organic matter, for their maintenance, growth and reproduction. Energy is derived from the breakdown of the chemical bond between carbon and either carbon or other components of compounds such as a phosphate ion .
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.
Scientists thought that Lake Enigma was frozen from top to bottom. Then they discovered that water—and mysterious lifeforms—existed 11 meters below the surface.
West coast states are spending millions to protect their inland waterways from invasive crabs. In some places, otters are just eating them.
Instead, these other decomposers live by absorbing and metabolizing on a molecular scale (saprotrophic nutrition). The terms detritivore and decomposer are often used interchangeably, but they describe different organisms. Detritivores are usually arthropods and help in the process of remineralization. Detritivores perform the first stage of ...
