Final answer:
Trees draw in water through their roots and release it into the air through their leaves, contributing to the cycling of water in the water cycle.
Step-by-step explanation:
Trees draw in water through their roots and release it into the air through their leaves. This process is called transpiration. Water moves from the ground into the roots of plants, then up through the stem to the leaves. Transpiration helps to add water vapor to the atmosphere, contributing to the water cycle.
