Answer:
Photosynthesis is a food or energy producing process.
Carbondioxode combines with water in the presence of light coming from the sun forming oxygen and glucose. In the process of photosynthesis, two products are produced i. e. oxygen and glucose. Oxygen is produced in the first stage of photosynthesis called light dependent reaction. The stage in which glucose is produced is Calvin cycle. It is the second stage of photosynthesis.
