Without them we could not live.
Living things. Some need water. Some need air. They could be pets to humans.
Living things that can talk and have feelings. They are sometimes called people. Are all different ages. Babes, Children, Teens, Adults, and the old.
Most of them need water to live. They give us carbon dioxide.
What humans drink. They can not live without water.
Humans can go without them for a few days. What humans eat.
