Answer 2

Answer:

Answer is Carbon Dioxide.  

Explanation:

Carbon dioxide is compound of carbon and two oxygen atoms. Plants absorb carbon dioxide from air and water from soil to prepare glucose, the first product, through a process known as photosynthesis.

Carbon dioxide supplies the carbon atom of glucose. So, the six molecules of carbon dioxide is required to make one molecule of the glucose.
