What happens to the carbon dioxide (CO2) levels of a plant when it does or does not have light?
zubka84 [21]

Explanation:

Carbon dioxide is needed for photosynthesis, but oxygen is needed for cellular respiration. Assuming there is still oxygen then the plants will produce carbon dioxide and some of it will be reabsorbed by photosynthesis during daylight. However, ultimately there wouldn’t be enough carbon dioxide for the plants to grow and they will start to die. Some plants have evolved a C4C4 photosynthesis pathway so they only require a small amount of CO2CO2 to survive, however they do still require more than zero CO2CO2.

So basically you killed off all the plants and all the other non-microbial life died of starvation shortly afterward.

Hope it helps...!! Please mark as brainliest
