Answer:
So photosynthesis requires energy from sunlight, water and carbon dioxide from the atmosphere in the presence of chlorophyll to produce glucose and release oxygen as by product.
That is: 6CO2+6H2O——————>C6H12O6+6O2
chlorophyll
Respiration,on the other hand,requires oxygen to breakdown glucose in order to release energy, oxygen and water vapor.
That is: 6O2+C6H12O6—>6CO2+6H20+ATP
