69. Students created food chains to learn how energy flows
through an ecosystem. After completing several chains,

A. No, because most animals only eat one type of food.
B. Yes, because most living things consume a variety of foods in
order to survive.
C. No, because producers make their own food.
D. Yes, because food chains and food webs are the same.
