Question 3 options:

PHOTOSYNTHESIS: where the carbon dioxide (CO2) is turned into glucose (C6H12O6)


CELLULAR RESPIRATION: where the glucose (C6H12O6) is turned into carbon dioxide (CO2)


DEFECATION: When an animal poops, carbon goes back into the soil


EATING: When animals eat, they take in the carbon from the atmosphere
