Carbon Circulation on Earth and Microorganisms

Abstract

At present, carbon occurs as carbon dioxide in the atmosphere in the ratio of 0.033% of air. Green plants (including algae and cyanobacteria) convert carbon dioxide to organic compounds by photosynthesis and evolve molecular oxygen. Animals eat the compounds and convert the compounds again to carbon dioxide. Thus carbon is circulated on Earth (Fig. 6.1.)
