As I understand, plants during divide the water molecule during the photosynthesis. If so, water molecules have to be created again somewhere in nature, where?
In: Biology
The water(H2O) plants intake is broken, leaving Hydrogen(H) and two Oxygen(O). The Oxygen(o2) is released, the Hydrogen(h) is combined with co2 in the plants photosynthesis cycle to be turned to sugars and used by the plant as food. Some of the water the plant sucks up from the soil is just evaporated back into the air going back to the water cycle as water vapor.
The vast bulk of the water on Earth is held in a closed system that prevents the planet from gradually drying out, but our atmosphere does have a lot of o2 which reacts with Hydrogen to create new water molecules too
