Water potentials decrease (become more negative) as one moves from soil to plant to atmosphere

Description
On land, water flows from the organism to the atmosphere at a rate influenced by the vapour pressure deficit of the air surrounding the organism. In the aquatic environment, water may flow either to or from the organism, depending on the relative concentrations of water and solutes in body fluids and the surrounding medium. But here too, water flows down its concentration gradient.
