Deciduous Trees Trivia Quiz – Falling Leaves and Bright Colors

Deciduous trees shed their leaves each year, usually in autumn in cooler climates or in the dry season in the tropics. Oaks, maples, beeches, birches and ashes are all deciduous, giving many temperate forests their changing seasonal look.

Dropping leaves saves water and energy when the ground is frozen and days are short. As autumn approaches, trees break down green chlorophyll, revealing yellow and orange pigments, and some make red anthocyanins. A special layer then seals the leaf stalk before it falls.

Autumn colors attract millions of visitors to places like New England, Kyoto and Canada. In spring, protected buds burst open with new leaves. Fallen leaves also feed the soil as they decompose, supporting fungi, insects and the next generation of trees.
