How is transpiration important to the water cycle?
It is the evaporation of water from the leaves of plants back into the atmosphere allowing the cycle to continue.
It results in the deposition of water vapor directly as ice, so water changes states causing the cycle to move to the next phase.
It allows plants to absorb water through their roots which is then precipitated back into the atmosphere.
It permits the diffusion of water from the surface to water tables deep underground which restores groundwater supplies.
