Which of the following prefigures the arrival of winter? leaves falling off trees flowers blossoming

Leaves falling off trees is a classic sign that fall is in full swing and winter is just around the corner. As temperatures drop, trees shed their leaves to conserve water and energy, entering a dormant state to survive the harsh winter months. It's nature's way of getting ready for the chilly days! On the other hand, flowers blossoming often indicates the arrival of spring rather than winter. In fact, the vibrant blooms springing up are a wonderful way for plants to celebrate the return of warmer weather. So, while those falling leaves are a signal of winter's approach, the flowers are busy ushering in the new season!
