Answer 1

The plant will produce enough food. Respiration in plants involve using the sugar produced during photosynthesis plus oxygen to produce energy for the plant while photosynthesis is the process by which plants use the energy from sunlight to produce glucose from carbon dioxide and water.Respiration involve using the sugar during photosynthesis plus oxygen to produce energy for the plant,in a natural environment plants produce food for their survival.

Answer 2

The reason for it is that the plant will take in same amount of carbon dioxide and give out the exact amount of oxygen, which will result in self sustainability.

But at the time of night, there is absence of photosynthesis.
