The deciduous forests are found in the North America, northeastern Asia, and western Eurasia. The trees in these forests exhibit thick bark, broad leaves and they shed their leaves in the winter season as these forests remain dry in winter seasons. These trees conserve water by shedding their leaves, as the water may loose by the process of transpiration. They regrow new foliage in the suitable growing season.
Therefore, green year around is the correct option as the decidous forests shed their leaves once in a year.
The green year a round trees are the evergreen trees, and they always remain green, they do not shed off their leaf completely at once. The deciduous forests are characterized by the presence of two seasons. In autumn, the deciduous forest shed off their leaves and become deprived of leaves and in spring, the new leaves come again.
