Decomposers are the link that keeps the circle of life in motion. [4][5] Unlike bacteria, which are unicellular organisms and are decomposers as well, most saprotrophic fungi grow as a branching network of hyphae. Only when the mold particles are joined together does it become visible, spreading out over a surface. Without microorganisms, especially bacteria and fungi, there is no significant amount of composting. Most examples of microorganisms in soil are decomposers . Many echinoderms are opportunistic carrion feeders or detritivores. She enjoys exploring the potential forms that an idea can express itself in and helping then take shape. Decomposers eat dead animals, or their wastage converts that into inorganic substances. It was very helpful but I wish it was not so long it took me two days to finish reading it. Echinoderms are mostly found in shallow waters, like coral reefs and intertidal rock pools, but can also be found in deeper waters. There are the six species which involve in decomposition. A decomposer is an organism that breaks down organic materials from dead organisms to obtain energy. Decomposers are the primary baseline of our ecosystem.
