You are presented with the quiz "In photosynthesis, plants convert solar energy, carbon dioxide, and water into what?" 

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 "fish are the consumers, and plants are the producers". 

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