Solution:
- Evapotranspiration (ET) is the sum of evaporation and plant transpiration from the Earth’s land and ocean surface to the atmosphere.
- Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies.
- Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapour through stomata in its leaves.
- Evapotranspiration is an important part of the water cycle. An element (such as a tree) that contributes to evapotranspiration can be called an evapotranspirator.
