You are presented with the quiz "What can't fungi make food with?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "fungi lack chlorophyll, so they cannot make food by photosynthesis as plants can" and "all plants require sunlight, carbon dioxide, and water for photosynthesis". 

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


 

 sunlight
