How do trees get water?

Trees primarily receive most of their water from the ground, so this is why trees are not seen in desert areas. They take the water into their roots and then they push the water up into the leaves and the leaves receive water also. The water then goes out into the atmosphere from the leaves in a process called transpiration. Trees also get water when it rains and if a person waters the tree, but trees have to rely on groundwater to survive.
