Question

What if during photosynthesis the amount of carbon-dioxide utilise d is comparativly becomes more than the amount of oxygen liberated?( What would be the consqco sequences)

Answer 1

Something similar happens in plants. When the rate of respiration is more than the rate of photosynthesis, the biomolecules present in plants break down to compensate the reduced rate of photosynthesis. This results in loss of dry weight of the plant.
