transpiration

As the air becomes hotter, it becomes easier for plants to lose water to transpiration, especially because photosynthesis occurs during daylight hours when temperatures are highest.

"We could exactly pinpoint how this is related to water transpiration and the ions the plant carries via the ascent of sap."

ET includes evaporation from soil and open water pools such as lakes, rivers, and ponds, as well as transpiration from plant leaves.

Scientists have a variety of methods to estimate the amount of water ascending from the Earth's surface to the atmosphere due to evaporation and transpiration through plant leaves.

As one plant loses moisture through the leaves, often called transpiration, the neighboring plants benefit.
