All the plants around you are breathing, too, and releasing water with every breath (although their breathing is much different than yours). The term is called "transpiration", and although a brussel sprout doesn't have a mouth, it has tiny holes in its leaves that allow water to leave the leaf and go back into the air. So, plants "transpire" water while humans "respire" and "persipire" water.
But the big word is "Evapotranspiration", which is just a combination of "evaportation" plus "transpiration". This just means that not only are plants transpiring water from their leaves, water is evaporating from the soil all around them.
