People are "animals". Animals can not make their own food they have to eat other animals and or plants to survive. Plants can make their own food (from air, water and sunlight) - they are the basis of all food - without plants there could be no animals.
Sunlight is very useful to people, plants, and animals. Without sunlight the world would become too cold, it warms the earth. It helps plants to grow, this provides food for people, and animals.
