  1. Quick Review: • What are the four forest biomes? • Where are they found? • Give at least one characteristic of each!

  2. Terrestrial Biomes 1. Temperate Grassland • Interior of North America (prairies), South America & Asia • Moderate rainfall, but too little for trees • Lightning-caused fires in summer • Root systems form dense layers to survive drought & fire • Soil is very fertile!

  3. Animals: antelope, bison, badgers, prairie dogs, burrowing owls, hawks • Threats: farming & overgrazing  soil erosion • Dust bowl 1930s

  4. 2. Savanna (tropical grassland) • Parts of Africa, South America, India, & Australia • Rain falls in spring & late-fall; drought in between • Plants: adapted to survive drought • Lose leaves; body parts die off except for near ground • Large, horizontal root system to collect water

  5. Animals: lots of big herbivores • Elephants, giraffe, antelopes, zebra, wildebeest, rhinos • Predators: lions, cheetahs, hyenas, crocs, snakes

  6. 3. Tundra • Found in northern arctic regions • Winters too cold & dry for trees to grow • Haspermafrost: permanently frozen soil layer • Plants: mosses & lichens • Dwarf shrubs – keeps plants out of wind & increased area for sunlight

  7. Animals: mosquitoes!, migratory birds, caribou, wolves, moose, mice, hares, foxes, polar bear • Threats: oil – pollution & habitat destruction

  8. Desert Biomes Desert = Low Precipitation 1. Tropical Desert • Ex: Sahara desert in Africa • Temperature changes during day: 100F + in day to cool at night; daytime temps hot all year long • Very few plants

  9. 2. Temperate Desert • North & South America, Asia, Australia • Daytime temps high in summer, low in winter • Plants: adapted to obtaining & conserving H2O • Cacti: thick, fleshy stems that store water; leaves have waxy cuticle

  10. Desert cont. • Animals: some mammals, snakes, lizards, tortoises • Have thick skin to prevent water loss • Amphibians burrow & go dormant during “dry” season • Most are nocturnal

  11. 3. Cold Desert • Ex: China’s Gobi Desert • Winters are quite cold, summers are warm/hot • Animals: lizards, gazelle, bactrian camel
