Another thing living things use water for is cleaning. Every animal clean then self, humans take baths and showers, but lions lick them selves and go in lakes.
A third thing that living things use water for is playing like squirt gun fights and other stuff to have fun. It doesn't help are every day life but we use water for it.
One other ways living things use water is to cool off. Like if you are in the desert for a couple hours you would probably use water to cool down.
One final way we use water is cooking. IN cooking you need water to make your food. Like rice you can't make it without water.
