उत्तर
By the way of photosynthesis in plants which occurs during daytime, carbon dioxide and water in the presence of sunlight and chlorophyll is changed into carbohydrates and oxygen is released out.
\[\ce{\underset{\text{(in air)}}{Carbon dioxide} + Water ->[sunlight][chlorophyll]\underset{\text{(glucose)}}{Carbohydrates} + Oxygen}\]
Hence, oxygen in the air is renewed by photosynthesis, and therefore the amount of oxygen in the air does not get depleted or removed from the air.
