Saprophagy

Saprophages are organisms that obtain nutrients by consuming decomposing dead plant or animal biomass.[1] They are distinguished from detritivores in that saprophages are sessile consumers while detritivore are mobile. Typical saprophagic animals include sedentary polychaetes such as amphitrites (Amphitritinae, worms of the family Terebellidae) and other terebellids.

Fungi are the primary decomposers in most environments, illustrated here Mycena interrupta.

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.

Ecology

In food webs, saprophages generally play the roles of decomposers. There are two main branches of saprophges, broken down by nutrient source. There are necrophages which consume dead animal biomass, and thanatophages which consume dead plant biomass.

gollark: I'm pretty sure prior art does stop someone from patenting your thing, if not making their own variants.
gollark: There's !!FUN!! with AV1/VP9 now where Google and such claim that there are no relevant patents, and a random patent troll claims that yes there are and you need to pay them money.
gollark: Guess? Wait for someone to complain?
gollark: They seem to at least work for patent trolls.
gollark: If you don't, you MAY be lawsuited.
