HELP!!!

What role do plants play in the carbon cycle?
A.
Plants release CO2 during photosynthesis, adding it to the atmosphere.
B. Plants use CO2 during photosynthesis, removing it from the atmosphere.
C. Plants use CO2 during respiration, removing it from the atmosphere.

Answer 1

b, plants use co2 during photosynthesis, removing it from the atmosphere

photosynthesis is 6CO2 + 6H2O → C6H12O6 + 6O2

respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O

therefore, it is not released during photosynthesis or used during respiration.
