Answer:
Chapter 2.
Step-by-step explanation:
Since the chapter is going to be talking about how animals have to get food and why it is difficult, you will find that "consumers" are included in this topic.
Consumers are organisms that eat other organisms to get energy. Therefore, in Chapter 2, you will be learning about organisms and how they get food, and consumers will be in that as well.
I hope this helps!
