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!
Day 3

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

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
Day 3

5. Animals: lots of big herbivores
Elephants, giraffe, antelopes, zebra, wildebeest, rhinos
Predators: lions, cheetahs, hyenas, crocs, snakes
Day 3

6. 3. Tundra Found in northern arctic regions
Winters too cold & dry for trees to grow
Has permafrost: permanently frozen soil layer
Plants: mosses & lichens
Dwarf shrubs – keeps plants out of wind & increased area for sunlight
Day 4

7. Threats: oil – pollution & habitat destruction
Animals: mosquitoes!, migratory birds, caribou, wolves, moose, mice, hares, foxes, polar bear
Threats: oil – pollution & habitat destruction
Day 4

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
Day 4

9. North & South America, Asia, Australia
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
Day 4

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
Day 4

11. Ex: China’s Gobi Desert Winters are quite cold, summers are warm/hot
3. Cold Desert
Ex: China’s Gobi Desert
Winters are quite cold, summers are warm/hot
Animals: lizards, gazelle, bactrian camel
Day 4

12. Temperate Deciduous Forest
