Therefore, decomposers are few and far between, either remaining dormant for long periods of time, or travelling vast distances in search of food. The most common decomposers in the ocean can be summarized as micro decomposers, marine worms, echinoderms, crustaceans, and mollusks. Decomposers eat dead animals, or their wastage converts that into inorganic substances. Often, when an animal dies, a scavenger, such as a vulture or hyena, will consume larger chunks of the body, but while scavengers do break down dead animals, they aren't decomposers, because they're not reducing the animal into chemicals that become part of the soil. Mussels eat some dead organic material and can be found on intertidal rocks. Or: food. Rather, these organisms range from simple one-celled soil Bacteria to multicellular Fungi. When two compatible fungi hyphae grow close to each other, they will then fuse together for reproduction, and form another fungus.[7]. Mollusks include mussels, clams, oysters, and snails.

After their death, microbes dissolved this nutrient again in the soil. For example, more than 100 species of Decomposers are the link that keeps the circle of life in motion. Differentiate between compostable waste and non-biodegradable waste. While this happens the detritivores are in the process of absorbing the nutrition and adding it to their own bodies, increasing their biomass. Examples; Salmonella enterica, Citrobacter farmer, Dickeya dadantii, Pectobacterium carotovorum, Brenneria salicis. These small creatures chew up bits of leaves, dead animals, or dead wood. Various species of bacteria play an important role in the breakdown of organic material. Large networks of mycelium can be found under dead leaves, straw, and grass, and they can run for miles underneath the soil.
