Which biome is characterized by layers of deciduous trees and four distinct seasons?

• A. Taiga
• B. Temperate deciduous forest
• C. Tropical rainforest
• D. Desert

Answer: (B)

The key idea is recognizing a biome by its seasonal cycle and how vegetation responds to it. A temperate deciduous forest features multiple vertical layers of vegetation—canopy, understory, shrub layer, and forest floor—and a pronounced four-season pattern. In these forests, many trees are deciduous, meaning they shed their leaves in autumn to survive the cold winter and then regrow them in spring. This creates the layered look you’d expect in such a forest and a clear seasonal rhythm with spring, summer, autumn, and winter.

This combination—layered structure and leaves that fall each autumn due to a cold season—fits temperate deciduous forests best. Taiga is dominated by evergreen conifers and has longer, harsher winters with less leaf turnover; tropical rainforests are warm and wet year-round with no true seasons; deserts are dry with minimal vegetation and no distinct four-season cycle.
