Distinguish between xeroohytes and hydrophytes.
(i) Tropical Deciduous Forests : These are found in subtropical regions with a distinct dry season. These forests have fewer species and are less dense. Teak is a valuable hardwood tree found in these forests. These are found in monsoon regions of Asia, central America, Brazil and northern Asia.
(ii) Mid-latitude Deciduous Forests : These occur in coastal regions of cool climates. Trees shed their leaves in winter when temperature is below 6°C. These occur in the region of western Europe, north-eastern China, Japan, north-eastern United States etc.
3. Grasslands: Grasses are shallow rooted plants which thrive under varying climatic conditions. They are divided into tropical grasslands and mid-latitude grasslands.
(i) Tropical Grasslands : These occur in the interiors of continents in the tropical zone. These grasses are tall, about 2 metres in height. These are found in equatorial regions of Africa, Brazilian Plateau, Deccan Plateau etc.
(ii) Mid-latitude Grasslands : These occur in the interiors of continents in mid-latitudes receiving moderate rainfall. These grasses are short and trees are absent. These are found in regions of Russia, U.S.A., Canada and South African plateau.
