Which consequence of a prolonged drought strongly inhibits capillary action within tree roots?

💡 Explanation

A drought causes root air embolisms, disrupting the continuous water column required for capillary action, because these block the xylem vessels. Therefore, water transport declines, rather than surface tension increases, because the critical path is pressure continuity.
