Scavengers are animals that consume dead organisms that have died from causes other than predation or have been killed by other predators. [1] While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding behavior. [2] Scavengers play an important role in the ecosystem by consuming dead animal and plant ...
In healthcare, green bottle fly larvae are sometimes used to remove necrotic (dead) tissue from non-healing wounds, [10] [11] and in waste management, black soldier fly larvae are used to convert decomposing organic waste into animal feed. [12] [13] Biotechnological applications for necrophage-derived genes, molecules and microbes are also ...
Many invertebrates, such as the carrion and burying beetles, [6] as well as maggots of calliphorid flies (such as one of the most important species in Calliphora vomitoria) and flesh-flies, also eat carrion, playing an important role in recycling nitrogen and carbon in animal remains.

The necrobiome has been defined as the community of species associated with decaying remains after the death of an organism. [1] The process of decomposition is complex. Microbes decompose cadavers, but other organisms including fungi, nematodes, insects, and larger scavenger animals also contribute. [2]
These insects do not feed directly on the decomposing remains or its fluids, but are considered to be the second most forensically important ecological role. [ 3 ] [ 7 ] Predators of necrophagous insects include species from the Coleoptera families Silphidae (carrion beetles) and Staphylinidae (rove beetles). [ 3 ]
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 remineralization, by fragmenting the dead plant matter, allowing decomposers to perform the second stage of ...
When animals eat seeds (seed predation or granivory) or eggs (egg predation), they are consuming entire living organisms, which by definition makes them predators. [6] [7] [8] Scavengers, organisms that only eat organisms found already dead, are not predators, but many predators such as the jackal and the hyena scavenge when the opportunity arises.
A given organism's ability to contribute to decomposition is largely dependent on what enzymes that organism possesses. Enzymes for the digestion of molecules like fats, proteins, and starch are widespread and many organisms, from microbes to mammals, have them. [9] As a result, those molecules are the first to decompose in the environment.
