What are the roles of the following in the carbon cycle organisms such as producers consumers and decomposers

The carbon cycle is the biogeochemical cycle, in which the plants (producers) take up carbon from air as carbon dioxide and convert it into glucose and other carbon containing compound, which is used by animals (consumers) in cellular respiration and produce carbon dioxide. The produced carbon dioxide is transferred back to the air. The organic material of the plants and the animals are buried in soil and their decomposition occurs, which is caused by the decomposition of the organic material into simple compounds by the decomposers. The decomposition causes the addition of the carbon in the soil.
