Why do deciduous trees shed leaves in dry season?
Answer and explanation
Correct answer: To reduce water loss through transpiration
During the dry season, less water is available in the soil. Water is lost through transpiration from stomata in the leaves, so deciduous trees shed their leaves to reduce this loss. Fallen leaves may later add humus to the soil, but that is not the main reason for leaf fall. Exam tip: remember that deciduous vegetation conserves water by shedding leaves in a dry period.
