True or false all living things must eat other living things for food

That is false because coyotes are cannibals in they survive in a pack

I would say True, even people who are Vegetarians eat "living foods" like fruits, vegetables, nuts and etc. are all considered living foods because they are all raw. especially meat . but then again it could be false because even though we are living does not mean we HAVE to eat living things for food, it just depends on what variety of foods you prefer
