Which risk occurs when a tall tree's photosynthetic rate sharply rises, while soil moisture lags at near zero?

💡 Explanation

Cavitation increases due to intense transpiration pulling water under high tension, because of low water availability. This causes air bubbles that break continuous water columns, therefore blocking xylem transport, rather than stomata or root structural changes that are slower responses.
