What term describes the loss of water that has been intercepted by vegetation and later becomes transpiration?

• A. Evaporation
• B. Runoff
• C. Infiltration
• D. Interception loss

Answer: (D)

Interception loss refers to the portion of rainfall captured by the vegetation canopy that does not reach the soil because it is stored on leaves and surfaces and is later returned to the atmosphere, often through the plant’s transpiration. This term specifically describes water that was intercepted and then leaves the plant as vapor, rather than water that evaporates from the surface or infiltrates the soil. It differs from evaporation from bare surfaces, infiltration into the ground, or surface runoff, which are other pathways of water loss.
