Which microorganism performs an essential role in the decomposition of organic matter and nutrient cycling and role of microorganisms in cycling of carbon?
Oribatida are actively involved in decomposition of organic matter, in nutrient cycling and in soil formation. Soil microbes can break down plant organic matter to carbon dioxide or convert it to dissolved organic carbon (DOC) compounds. This leads either to long-term carbon storage, because DOC can bind to soil particles, or to the release of carbon back to the atmosphere as carbon dioxide. Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers. The role of decomposers is ecologically essential as they recycle nutrients through a natural biological process as decomposers are fungi and bacteria that obtain their nutrients from a dead plant or animal material.
Microorganisms help return minerals and nutrients back to the environment so that the materials can then be used by other organisms. As the bacteria and fungi decompose dead matter, they also respire and so release carbon dioxide to the environment, contributing to the carbon cycle .Soil microbes can break down plant organic matter to carbon dioxide or convert it to dissolved organic carbon (DOC) compounds. This leads either to long-term carbon storage, because DOC can bind to soil particles, or to the release of carbon back to the atmosphere as carbon dioxide. The microbe plays an essential role of organic matter degradation in nutrient cycling; microorganism present in soil digests the organic matter including dead organisms. The nutrients get released by the breakdown of the organic molecule to make it available for plants to uptake nutrients in the soil through roots. A broad range of bacteria, archaea and fungi are capable of denitrification, comprising approximately 50% of known phylogenetic groups with cultivated representatives. Denitrification, like nitrification, is essential for the soil nitrogen cycle, returning nitrogen to the atmosphere. Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers. Decomposition by soil organisms is at the center of the transformation and cycling of nutrients through the environment. Decomposition liberates carbon and nutrients from the complex material making up life forms-putting them back into biological circulation so they are available to plants and other organisms.
Bacteria and fungi are responsible for most of the mineralisation of organic matter in soils. Microorganisms release enzymes that oxidise the organic compounds in organic matter. The oxidation reaction releases energy and carbon, which micro-organisms need to live. A broad range of bacteria, archaea and fungi are capable of denitrification, comprising approximately 50% of known phylogenetic groups with cultivated representatives. Denitrification, like nitrification, is essential for the soil nitrogen cycle, returning nitrogen to the atmosphere. The primary decomposers release extracellular hydrolytic enzymes into their immediate environment and these catalyze organic matter decomposition. These may be the macroscopic organisms such as earthworms and nematodes or microorganisms such as fungus, actinomycetes and bacteria. These organisms breakdown the plant material into soil organic matter. Earthworms benefit soil in several different ways. They begin the cycle of decomposition for organic matter. By far the most important microscopic decomposers are bacteria, which do the lion's share of decomposition in the compost heap. But there are other microscopic creatures such as actinomycetes, fungi, and protozoa that also play an important role. Decomposers have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting. The microbe plays an essential role of organic matter degradation in nutrient cycling; microorganism present in soil digests the organic matter including dead organisms. The nutrients get released by the breakdown of the organic molecule to make it available for plants to uptake nutrients in the soil through roots. Nature has its own recycling system: a group of organisms called decomposers. Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces.
