You are presented with the quiz "What do fungi lack that make them unable to make food as producers can?" 

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 "if the plant is green, it is a producer". 

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


 

  chlorophyll
