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 ...
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 ...
[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.
The main nutrients plants have to derive from soils are nitrogen, phosphorus, and potassium, and all three have to be available in forms that are accessible to and absorbable by the plants. Decomposition is the process of breaking large molecules in dead matter down into smaller molecules that nearby plants are able to take up through their roots.
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 body of a rotifer is divided into a head, trunk, and foot, and is typically somewhat cylindrical. There is a well-developed cuticle, which may be thick and rigid, giving the animal a box-like shape, or flexible, giving the animal a worm-like shape; such rotifers are respectively called loricate and illoricate. Rigid cuticles are often ...
Filled with live plants, substrates, and glimmering schools of fish, a perfectly curated aquarium is an awe-inspiring art form. ... They’ll devour extra fish food, hoover up dead organisms, and ...
Organisms feed on dead organic remains of other organisms. Many fungi: Parasitic nutrition: Organisms obtain food from other living organisms (the host), with the host receiving no benefit from the parasite. When a parasite is present inside the body of the host, it is known as an endoparasite. These parasites suck and feed on the blood of the ...
