Answer:

The animals in polar region have thick fur and thick skin to protect themselves from the cold climatic conditions.  Tropical deciduous trees shed their leaves in the dry season to conserve water. The type and thickness of vegetation changes from place to place because of the variation in the factors like temperature, moisture, slope and thickness of soil.
