In the carbon cycle, what purpose do the bacteria serve?

• They absorb carbon dioxide from the atmosphere and convert the carbon into glucose for organisms to consume.

• They act as a reservoir for carbon by storing it in the form of dissolved organic carbon.

• They break down carbon from decaying organisms and release the carbon as carbon dioxide.

• They convert glucose from living organisms into energy and release the carbon in the form of carbon dioxide.
