Detailed explanation-1: -Deciduous forest trees are those that lose their leaves in the winter. The leaves are important for photosynthesis, so deciduous trees must go dormant in the winter, when there is not enough light to do photosynthesis.

Detailed explanation-2: -Leaves change color (or senesce) in autumn, fall off in the winter, and grow back in the spring; this adaptation allows plants to survive cold winters.

Detailed explanation-3: -Complete answer: In temperate forests in the Northern Hemisphere, trees shed their leaves during autumn as a cold season. In tropical and subtropical forests, trees shed their leaves at the beginning of the dry season. Many types of trees shed their leaves as a strategy to avoid harsh weather conditions.

Detailed explanation-4: -Temperatures in temperate forests fluctuate; there are defined growing seasons during spring, summer, and early fall. Because temperate forests have moderate annual precipitation, the dominant plants are the deciduous trees.

Detailed explanation-5: -Trees that drop their leaves in autumn are called deciduous trees. Oaks, elms, ash, and beeches are a few of the deciduous trees that can grow in temperate forests. Some temperate forests have trees with needles rather than leaves. Trees that have needles and cones, like pine cones, are called conifers.
