Question

How you prove that carbon dioxide is necessary for photosynthesis?

Answer 1

yes. like us, how we breath oxygen, plants breath carbon dioxide. so without it the photosynthesis process will not be complete. As carbon dioxide increases, the rate of photosynthesis increases. For example if we put soda lime (absorbs carbon dioxide) with the plant and cover it with a plastic bag, the plant will be lacking carbon dioxide and the rate of photosynthesis will decrease.
