  • 1. WORLD BIOMES
  • 2. DECIDIOUS FOREST LOCATION: eastern North America, northeastern Asia, and western and central Europe. CLIMATE: winter characterize this forest biome. Temperature varies from -30° C to 30°C.Precipitation (75-150 cm) is distributed evenly throughout the year. PLANTS: Canopy is moderately dense and allows light to penetra.Flora is characterized by 3-4 tree species per square kilometer. Trees are distinguished by broad leaves that are lost annually. ANIMALS: is represented by squirrels, rabbits, skunks, birds, deer, mountain lion, bobcat, timber wolf, fox, and black bear.
  • 3. SAVANA • LOCATION: central Africa and large areas of Australia, South America, and India • CLIMATE: warm or hot climates . Rainfall is concentrated in six or eight months of the year, followed by a long period of drought when fires can occur. • PLANTS: vegetation consists of grasses and forbs (small broad-leaved plants that grow with grasses) • ANIMALS: include giraffes, zebras, buffaloes, kangaroos, mice, moles, gophers, ground squirrels, snakes, worms, termites, beetles, lions, leopards, hyenas, and elephants.
  • 4. TAIGA LOCATED: north of Asia, north of North America CLIMATE: Seasons are divided into short and moderately warm summers and long, cold, and dry winters. Low temperature.Precipitation is primarily in the form of snow, 40-100 cm annually. PLANTS:Canopy permits low light penetration and understory is limited.Consist mostly of cold-tolerant evergreen conifers with needle-like leaves, such as pine, fir, and spruce. ANIMALS:Include woodpeckers, hawks, moose, bear, weasel, lynx, fox, wolf, deer, hares, chipmunks, shrews, and bats.
  • 5. TUNDRA • LOCATION: north of North America, north of Asia and Artic. • CLIMATE: extremely cold, little precipitation. • PLANTS: All of the plants are adapted to winds. Plants are short and grow in groups to resist the cold temperatures and are protected by the snow during the winter. • ANIMALS: Animals are adapted to resist cold winters .Many animals hibernate during the winter because food is not abundant. Another migrates south in the winter, like birds . Reptiles and amphibians are few or absent because of the extremely cold temperatures. Because of constant immigration and emigration, the population continually oscillates.
  • 6. HOT DESERT LOCATION: North American, South and Central America, Africa and Australian. CLIMATE: Warm seasons during the year , very hot summers .Minimum temperatures ranges to 20- 25°C and maximum to 44-49°C. Low rain fall. PLANTS: Plants are mainly ground-hugging shrubs and short woody trees. Leaves are “replete” with water and nutrients. They tend to be small, thick and covered with a thick protection.In the cacti, the leaves are reduced (to spines) and photosynthetic activity is restricted to the stems. ANIMALS: The dominant animals are burrowers and kangaroo rats. There are also insects, arachnids, reptiles and birds. The animals stay inactive in protected hideaways during the hot day and come out at night, when the desert is cooler.H
  • 7. TROPICAL FOREST • LOCATION:near the equator • CLIMATE:winter is absent, only two seasons are present (rainy and dry). The length of daylight is 12 hours .Temperature is on average 20-25° C .Precipitation is evenly distributed throughout the year, with annual rainfall exceeding 2000 mm. • PLANTS: Canopy in tropical forests is multilayered and continuous, allowing little light penetration. • Flora is highly diverse: one square kilometer may contain as many as 100 different tree species. Trees are 25-35 m tall, with buttressed trunks and shallow roots, mostly evergreen, with large dark green leaves. Plants such as orchids, bromeliads, vines (lianas), ferns, mosses, and palms are present in tropical forests. • ANIMALS:Fauna include numerous birds, bats, small mammals, and insects.
