  2. Tundra Region -Northern most region adjoining the ice bound poles Flora and Fauna- Devoid of trees except stunted shrubs in the southern part of tundra biome, ground flora includes lichen, mosses and sedges. The animals are reindeer, arctic fox, polar bear, snowy owl, lemming, arctic hare, ptarmigan. Reptiles and amphibians are almost absent. . Taiga .Region Northern Europe, Asia and North America. Moderate temperature than tundra Also known as boreal forest Flora and Fauna- The dominating vegetation is coniferous evergreen mostly spruce, with some pine and firs .Fauna consists of small seed eating birds, hawks, fur bearing carnivores, little mink, elks, puma, Siberian tiger, wolverine, wolves etc.

  3. Temperate Deciduous Forest Region Extends over Central and Southern Europe, Eastern North America, Western China, Japan, New Zealand etc. Moderate average temperature and abundant rainfall. These are generally the most productive agricultural areas of the earth . The flora includes trees like beech, oak, maple and cherry Most animals are the familiar vertebrates and invertebrates. Tropical rain forest .Region Tropical areas in the equatorial regions, which is abound with life. Temperature and rainfall high. Tropical rainforest covers about 7% of the earth's surface & 40% of the world's plant and animal species. Multiple storey of broad-leafed evergreen tree species are in abundance. Most animals and epiphytic plants are concentrated in the canopy or tree top zones.

  5. Savannah Tropical region: Savanna is most extensive in Africa.Grasses with scattered trees and fire resisting thorny shrubs The fauna include a great diversity of grazers and browsers such as antelopes, buffaloes, zebras, elephants and rhinoceros; the carnivores include lion, cheetah, hyena; and mongoose, and many rodents. Grassland Region -North America, Ukraine, etc. Dominated by grasses. Temperate conditions with rather low rainfall The fauna include large herbivores like bison, antelope, cattle, rodents, prairie dog, wolves, and a rich and diverse array of ground nesting bird.

  6. Desert . Region Continental interiors with very low and sporadic rainfall with The flora is drought resistance vegetation such as cactus, euphorbias, Aquatic Zones low humidity. The days are very hot but nights are cold. sagebrush. Fauna: Reptiles, Mammals and birds. Aquatic systems are not called biomes, however they are divided into distinct life zones, with regions of relatively distinct plant and animal life. The major differences are due to salinity, levels of dissolved nutrients; water temperature, depth of sunlight penetration Fresh water ecosystem are classified as lotic (moving water) or lentic (still or stagnant water). Lotic water system includes freshwater streams, springs, rivulets, creeks, brooks, and rivers. Lentic water bodies include pools, ponds, some swamps, bogs and lakes. They vary considerably in physical, chemical and biological characteristics.
