Both of these different types of worms feed on by organic material such as algae, fungi, and other microorganisms found on these materials. Micro-organisms (the decomposers) break down the proteins in excretions and dead organisms, releasing ammonium ions. The ones that live on dead materials help break them down into nutrients which are returned to the soil. Other important decomposers include less well-known crustaceans like sea louse and microscopic planktonic crustaceans such as krill or water fleas8. Leaves, twigs and pieces of bark that have fallen to the ground make up leaf litter. Where are the decomposers in a food chain? There are three types of marine fungi: harmless decomposers that eat dead organic matter, symbiotic fungi that live in harmony with their host, and parasitic ones that feed on animals or plants. Decomposers are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi. This is especially true during the early stages of decomposition. Some are pathogenic, while some are harmless. Marine Microbes. Since no photosynthesis can take place, deep ocean ecosystems have low levels of organic matter and mostly rely on influx of organic matter from shallower waters. Earthworms are the best example of decomposers because they live inside the soil and are easy to find, especially after it rains.
