Q1) What is dry deciduous forest ?
A dry deciduous forest is a type of forest ecosystem characterized by specific environmental conditions and a particular composition of plant and animal species. These forests are found in regions with distinct dry and wet seasons, where the trees shed their leaves during the dry season to conserve water. These are typically found in areas with a tropical or subtropical climate.
