How do microorganisms influence the carbon cycle on Earth?

1 Answer

Answer :

Most of the organic matter present in soil originates in plant material from leaves, rotting trees, decaying roots, and other tissues. In the carbon cycle, soil bacteria and fungi recycle this carbon by using the organic matter in their metabolism. Without the recycling action of these organisms, life would suffer an irreversible decline as the nutrients essential for life became tied up in complex molecules.
