Minchanka [31]
Because it has the ability to get light, photosynthesis would happen. Since it is in an airtight jar, it will use all the CO2 in the jar until all the CO2 is gone and there is only Oxygen left. Photosynthesis's rate will decrease rapidly. After that, the plant will have no more energy since there is no CO2 to allow it to keep with photosynthesis, so it would die off.
