The  Savanna Biome  is a product of the tropical wet-dry climate. Vegetation changes  from woodland to thorntree grassland with increasing dryness. The adaptation to  dryness includes deciduous habit and small leaves or thorns.  The  Grassland Biome  is found in the midlatitude and subtropical zones which have  well developed winter and summer seasons. The biome includes both tall-grass prairie  and steppe. Steppe vegetation grows in the semi-arid subtype of the dry continental  climate.  The  desert biome  includes both desert and semi-desert subtypes. The area of semi- desert ranges from the tropical to the midlatitude zone. The vegetation includes sparse  xerophytic shrubs and in some areas thorny trees and shrubs are adapted to a long hot  dry season with a short wet season. Desert vegetation ranges from small hard leafed or

Unformatted text preview: spiny shrubs, succulent plants and hard grasses to many areas with no vegetation covered by shifting sands and salt flats. The tundra biome is found at high latitudes and high elevations. Plants include low herbs, dwarf shrubs, sedges, grasses, mosses and lichens. At high latitudes plant growth is influenced by long winters with little light and short cool summers with very long days. Permafrost underlies the surface and restricts drainage and root development. As elevation increases, temperatures decrease and precipitation increases leading to a sequence of vegetation zones or life zones related to altitude. Climate changes with latitude and longitude are reflected in changes in vegetation. These changes are gradual not abrupt....
