Final answer:

Plants use the process of abscission to shed leaves in response to changing environmental conditions.


Explanation:

Abscission is the process by which plants shed leaves. This process is regulated by interactions between auxin and ethylene in response to changing environmental conditions.

During the growing season, high levels of auxin produced by young leaves block the activity of ethylene, keeping the leaves attached to the stem. However, as seasons change and auxin levels decrease, ethylene triggers leaf senescence, leading to leaf shedding.
