Which of these organisms is involved in the carbon cycle? Which step is it involved in? What is happening during this process with this organism?

• Plants; transpiration; water released by plant re-enters atmosphere

• Humans; combustion; burning of different carbon rich materials including fossil fuels

• Bacteria; nitrogen fixation, ammonification, nitrification, denitrification; convert atmospheric N to usable N, convert N to ammonia, etc.

• Never uses living organisms; no process; no description
