What is the combined loss of water from plants by both evaporation and transpiration called?

• A. Evapotranspiration
• B. Evaporation
• C. Transpiration
• D. Runoff

Answer: (A)

Plants lose water in two ways: evaporation from surfaces (like soil, water, and plant surfaces) and transpiration through the leaves’ stomata. When you combine these two processes, the total water loss is called evapotranspiration. This term is used in hydrology and agriculture to describe how much water is removed from a landscape by both evaporation and plant uptake. Evaporation alone refers only to water turning into vapor from surfaces; transpiration alone is water lost from within the plant through the leaves. Runoff, on the other hand, is water that flows over the surface and does not involve plant water loss.
