Decomposer: Decomposers are earthworms, fungi, and bacteria. It can be also called a detritivore since a scavenger relies on the waste materials. Are Giant Insects Larger Than Humans Possible? Similarly, detritivores are also involved with the decomposition of the dead organic matter. This is the difference between decomposer and detritivore. For the uninitiated, detritus is organic matter composed of dead trees, plants and animals. Difference between Detritivores and Decomposers. Worms living on the surface or upper layers of the soil feed on fallen leaves or dead grass. Scavenger: Scavengers are mainly animals. The detritivores are responsible for the intake of large particles of dead organisms. They feed on dead plant and animal matter and then digest them within their bodies in order to gain nutrients and energy. The detritivores are responsible for consuming large particles of the deceased organisms. Organisms such as earthworms, woodlice, sea stars, slugs, and fiddler crabs are good examples of detritivores. 1.“Decomposer” is a general term while detritivores are one of the classifications of decomposers. Detritivores refers to the class of organisms that feeds on detritus or organic waste. Detritivores are actually a type of saprotrophs. The image above shows mushrooms (fungi) growing in the Elatia forest near Greece. Scavenger: Scavengers breakdown large organic materials into small pieces. Decomposition is a chemical reaction where a complex compound is broken down into simpler compounds. This cast is simply a more processed version of the consumed food and soil with nutrients that have been broken down enough to be decomposed by microorganisms. is passed out from the body of the worm. “Decomposers” by USFWSmidwest (CC BY 2.0) via Flickr2. They differ in the nature of their diet, the way of decomposition, and the way they eat. Not only do they help in completing various carbon or nitrogen cycles through the recycling of nutrients, but they also help to remove dead and decaying matter that could otherwise lead to the spreading of disease. This material is dissolved organic material called detritus. By this action, the deceased organism is then more exposed to decomposers as portions of the organism would be exposed to the decomposers as detritivores eat away from the dead organism. They use chemicals that eat dead organisms. Most soil bacteria also serve as decomposers. Also, both involve with the decomposition of dead plant and animal organic matter. Most decomposers are in the form of bacteria or fungi that are detritivores come in different forms, e.g. 3. When A Hurricane Strikes, What Happens To Marine Animals Living Below It? Bacteria and fungi are good examples of decomposers that feed on dead and decaying organic matter. All rights reserved. Both these types of organisms recycle nutrients in the ecosystems. ... Dead Plants, Decomposer, Detritivores, Ecosystem, Saprotrophs, Scavenger What is a Scavenger. Available here, 1.”A fungus on a dead tree”By Yuna Werchner – Own work, (CC BY-SA 4.0) via Commons Wikimedia   Decomposers are manly fungi. Can We Harness Electricity From Lightning? As the name implies, decomposer is an organism that aids in the decomposition of already dead or dying organisms including mainly plants and animals. - Detritus: dead animals or plants and feces - Action of detritivores increase the activities of decomposers - Examples: snails, slugs, termites, spiders, earthworms (The most abundant detritivore), mites, starfish, crabs Both decomposers and detritivores can be termed as heterotrophic, but it hardly implies that they are same. The decomposers and the detritivores also play a major role in the life cycle in the ecosystem. They use powerful enzymes to break down some of the deceased organism, and transform them into simpler substances. Another essential difference between the detritivore group and the decomposers is that decomposers mostly occur across nature in the form of fungi or bacteria whereas detritivores come in different forms, e.g. Summary. Learn vocabulary, terms, and more with flashcards, games, and other study tools. It can be also called a detritivore since a scavenger relies on the waste materials. They are the initial instigators of decomposition. How does the world make it so far without new virus development? 2. 3.Most decomposers are in the forms of bacteria or fungus whereas the detritivores come in different forms, namely; worms, millipedes, woodlice, dung flies, and slugs in the terrestrial aspect. Both scavenger and decomposer breakdown organic materials. Compare the Difference Between Similar Terms. Why Are There Stones Along Railway Tracks? Detritivores consume detritus and the decaying forms of producers or consumers.
