(b) Arctic tundra- This region lies in the higher latitudinal areas extending from the arctic to the extreme poles. The temperature here is extremely cold and precipitation is low. The plants and trees here are short in height.
(c) Temperate grassland- These are the mid-latitude areas covering the extensive grasslands of both the northern and the southern hemisphere. The temperature and precipitation level here are both moderate.
(d) Tropical rain forest- These are the regions that covers the vast rain forest areas in the tropical region of both the hemispheres.
