Discuss the important of bacteria in biogeochemical cycle

... A scavenger may eat the carcass, but its feces still contains a considerable amount of unused energy and nutrients. This last step releases raw nutrients (such as nitrogen, phosphorus, and magnesium) in a form usable to plants, which quickly incorporate the chemicals into their own cells. This process greatly increases the nutrient-load of an ecosystem, in turn allowing for greater biodiversity. The carbon cycle includes four main reservoirs of stored carbon: as CO2 in the atmosphere; as organic compounds in living or recently dead organisms; as dissolved carbon dioxide in the oceans and other bodies of water; and as calcium carbonate in limestone and in buried organic matter (e.g. natural gas, peat, coal, and petroleum). Ultimately, the cycling of carbon through each of these reservoirs is tightly tied to living organisms. Plants continuously extract carbon from the atmosphere and use it to form carbohydrates and sugars to build up their
