Which consequence results in tall trees when atmospheric pressures decrease significantly?

💡 Explanation

Lower pressures increase the vapor pressure gradient, thereby accelerating water evaporation; this increases tension in xylem leading to xylem cavitation. This bubble formation disrupts the cohesion-tension mechanism because air blocks water transport, therefore, less water available, rather than enhanced transport through xylem.
