In carbon cycle, carbon is mainly present in the form of carbondioxide gas. This carbondioxide is absorbed by the plants from the atmosphere and used as a raw material for the production of food materials such as glucose in the process of photosynthesis. When this food is eaten by living organisms, this food is used for the production of energy in the process of respiration which produces energy, water and carbondioxide. This carbondioxide is released in the atmosphere through breathing and the cycle is completed and starts again.
