Decomposer biology definition : An organism whose ecological function involves the recycling of nutrients by performing the natural process of decomposition as it feeds on decaying organisms.
Each trophic level in a food chain or an ecological pyramid is occupied by a group of organisms that have a similar feeding mode. There are three fundamental groups of living things classified based on feeding modes.
These are producers, consumers , and decomposers. Producers are the ones that obtain nourishment directly from inorganic sources. Consumers are the ones that feed on organic matter.
Decomposers are those that break down dead organic material and wastes. They are eukaryotic organisms. They are characterized by the presence of chitin in the cell wall as opposed to the cell wall of plants and some bacteria, which are largely made up of cellulose and peptidoglycan , respectively.
Ecological role: the role of decomposers is ecologically essential as they recycle the nutrients through a natural biological process decomposition.
Examples of decomposers are fungi and bacteria that obtain their nutrients from a dead plant or animal material. They break down the cells of dead organisms into simpler substances, which become organic nutrients available to the ecosystem. Organisms that break down decaying organisms Producers. All of the following are the general characteristics of fungi except for Photosynthetic. Specifically feed on dead or decaying organisms Saprophytes. How are earthworms an important decomposer?
They absorb nutrients from organic matter. They enrich soil when breaking down litter. They enhance digestion in the intestinal tract.
Which of the following are not decomposers? Dung beetles. Send Your Results Optional. Your Name. To Email. Time is Up! The Human Physiology Physiology is the study of how living organisms function. Animal Water Regulation Animals adapt to their environment in aspects of anatomy, physiology, and behavior. Physiological Homeostasis Homeostasis is essential to maintain conditions within the tolerable limits.

Examples of decomposers: fungi, bacteria, earthworms, insects. Examples of detritivores: millipedes, earthworms, crabs, flies, etc. Decomposers act on the dead matter, e. Detritivores contribute to the decomposition process, particularly, by ingesting the dead matter, and then digesting it in their digestive tract.
Decomposers cannot act on the clumps of the dead matter. Detritivores can feed upon large clumps of the dead matter. Initiate the process of the decomposition by breaking down the dead mass into small particles.
Act on the small particles that are made available due to the action of scavengers and break down further to yield the basic elements like, carbon, calcium, phosphorous, etc. Initiators of the decomposition process. The Sahara is the largest hot desert in the world and is located in North Africa, spanning nine countries.
World View. What Are Decomposers in the Sahara Desert? More From Reference. What Colors Make Blue? War Veteran Monuments and Memorials. Many of the desert decomposers you can find are insects. Grassland decomposers can sometimes be found in forests or deserts since those are similar environments. As you can see, certain types of insects and fungi are the most common decomposers in a variety of ecosystems. You can explore more specific species examples to see how different types of beetles or worms, for example, break down dead matter.

Examples of Decomposers in Aquatic Ecosystems Aquatic decomposers live in water-based environments that are marine or freshwater. Examples of Decomposers in Oceans There are more decomposers in tropical oceans, like the Pacific, because of the warmer temperatures.
