Answer 1

Plants are mostly made of carbs (including fibre, which is kind of just “carbs too chewy for us to digest”). Carbs are made out of oxygen, carbon, and hydrogen. Water gives you oxygen and hydrogen, carbon dioxide from the atmosphere gives you carbon and more oxygen, and sunlight gives you the necessary energy supply to fuel the chemistry that turns water+air into carbs.
