Students designed an experiment to model the carbon cycle. The students combined water & carbon dioxide-producing disks in a sealed flask. The flask represented earth's atmosphere, and the lamp represented the sun.

Which component can be added to the flask to reduce the concentration of carbon dioxide in the model atmosphere created by the discs?

• Bacteria to use carbon during nitrification.

• Plants to absorb carbon in the process of photosynthesis.

• Snails to use carbon through cellular respiration.

• Mushrooms to absorb carbon during decomposition.
