Decomposers can break down dead things, but they can also feast on decaying flesh while it's still on a living organism. Explanation: If decomposers were removed from a food chain, there would be a break down in the flow of matter and energy. Human activities, such as pollution, can result in a plankton bloom. 1.Introduction. Vancouver, BC Decomposers are just a way for Mother Nature to keep her habitats clean. But with all of their features. These organisms are so important for the topsoil because they help chemically break down organic material in the early stages. Center for microbial oceanography: research and education. What will happen if we remove decomposers from an ecosystem? Plant growth would decrease over time as the nitrogen the plants took from the soil was not replaced. Mushrooms have an important role as a decomposer. Given enough time, all biodegradable material will oxidize to humus. Examples of decomposers include bacteria, fungi, some insects, and snails, which means they are not always microscopic. As we will see, chemosynthetic bacteria can also be regarded as decomposers to some degree. Most mollusks prefer shallower waters. Whereas the sulfur-loving bacteria often found around whale carcasses and thermal vents mentioned above create their own energy via a process known as chemosynthesis, most bacterial species in the ocean are true heterotrophic decomposers.
