Which process involves the loss of water vapor to the atmosphere from living plants?

The process that involves the loss of water vapor to the atmosphere from living plants is transpiration. This natural phenomenon occurs as plants absorb water from the soil through their roots and then release it into the air primarily through small openings on the leaves called stomata. Transpiration plays a crucial role in the water cycle, as it contributes to humidity and helps regulate temperature in the surrounding environment.

This process not only aids in the movement of nutrients within the plant but also helps maintain the plant's internal water balance. It is vital for photosynthesis, as it enables the uptake of carbon dioxide, which is necessary for the production of energy in plants. In summary, transpiration is a fundamental biological and environmental process that highlights the connection between plants and the atmosphere.
