What term describes the combined process of water loss by both plant transpiration and soil surface evaporation?
Explanation
The term 'Evapotranspiration' refers to the total water loss from the soil and plants, combining evaporation from the soil surface and transpiration from vegetation. Transpiration is only water loss from plants, evaporation is water loss from soil or water bodies, and guttation is the exudation of water droplets from leaf edges.
