Which event follows when a tall tree transpires excessively during drought?

💡 Explanation

When transpiration exceeds the water flow in drought scenarios, cavitation leads to embolism because the Cohesion-Tension mechanism within the xylem fails due to excessive negative pressure; therefore, air bubbles block water transport rather than maintaining efficient water movement.
