Carbon from dead leaves is recycled through the carbon cycle. Explain how Carbon is recycled to new leaves.

Dead leaves fall from plants to the ground. These leaves contain carbon. They are digested by microorganisms like bacteria which take up carbon and then respire it into the atmosphere. Plants are autotrophs and take carbon dioxide from the atmosphere via photosynthesis. Photosynthesis converts carbon dioxide to glucose which is needed to synthesise amino acids, proteins and cellulose. These are all required for plants growth.
