1 Biomes A Whirlwind Tour of Life on Earth

2 Tropical Forests near equator in S. America and Africa
inches/year of rain 80oF average temperature high biodiversity complex structure many levels of life Monkeys and snakes lianas, epiphytes woody vines, hanging plants

3 Coniferous Forest taiga
northern Eurasia, N. America, northern California coast spruce, fir, and pines thick bark and leaves that withstand snow fungi, mosses, lichens grow due to needle canopy some of worlds tallest trees redwoods

4 Deciduous Forests south of taiga in eastern N. America, eastern Asia, and much of Europe 30-40 in/year of rain deciduous trees oak, hemlock, maple well-developed understory plentiful animal life

5 Deserts Arizona, Saudi Arabia, Africa rainfall less than 10 in.
hot days, cold nights lack vegetation contain succulents plants that store water insects thrive during rain lizards, snakes, birds, rodents, predator mammals abundant

6 Grasslands rainfall 10-30 inches/year savanna African grassland
“The Lion King” prairie temperate grassland Midwestern U.S. much converted to farmland grazing animals (bison, pronghorn antelope) small mammals (praire dogs, mice, snakes, coyotes) many animals live in burrows

7 Tundra arctic and alpine tundras
arctic is cold, dark, and dry ( 6-10 inches) thick layer of permafrost simple vegetation sedges, mosses, grasses caribou, polar bears, sandpipers, flies, salmon
