Microorganisms play a significant role in breaking down organic matter quickly. The process in which helpful bacteria and vermin, such as red worms, recycle matter into fresh soil is composting. The decomposers, nutrients get added back to the soil or water, so the producers can use them to grow and reproduce. Micro organisms play a significant role in biodegradation of oil in the marine ecosystem. The type of organism that recycles nutrients in a food web is decomposers. Decomposers are organisms that consume dead or decaying matter and recycle the nutrients back into the soil. Bacteria break down (or decompose) dead organisms, animal waste, and plant litter to obtain nutrients. But microbes don't just eat nature's waste, they recycle it. The process of decomposition releases chemicals (such as carbon, nitrogen, and phosphorus) that can be used to build new plants and animals. Microorganisms play a significant role in breaking down organic matter quickly. The process in which helpful bacteria and vermin, such as red worms, recycle matter into fresh soil is composting. Bacteria change the soil environment so that certain plant species can exist and proliferate. Where new soil is forming, certain photosynthetic bacteria start to colonize the soil, recycling nitrogen, carbon, phosphorus, and other soil nutrients to produce the first organic matter. Soil microbes play an important role in nutrient recycling. They decompose organic matter to release nutrients. They are also important to trap and transform nutrients into the soil, which can be taken up by plant roots. Nutrient cycling rate depends on various biotic, physical and chemical factors.
