You are presented with the quiz "What is produced by leaf cells as a carbohydrate by producers?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "photosynthesis means producers convert from carbon dioxide, water, and solar energy into carbohydrates for themselves" and "leaf cells produce sugar by photosynthesis". 

So, what's the best answer to the question?


 

 sugar
