Answer: The carbon to produce carbohydrates in second stage of photosynthesis comes from CARBONDIOXIDE.
Explanation:
Photosynthesis is the process by which green plants use light energy from sunlight with carbon dioxide and water to produce glucose.
This involve two stages; the light dependent and light independent stage(dark stage).
The light independent is the second stage and it uses carbon atoms from carbondioxide , which gas exhaled by animals to produce carbohydrates. It is also referred to as Calvin cycle because it used energy stored by the light dependent stage to form carbohydrates.
