3. Abiotic Factors that characterize the Desert Biome  Driest Biome on Earth!  Hot Deserts and Cold Deserts  Very little rainfall – less than 9 inches per year  Temperatures in Hot deserts range depending on the latitude lines.  Some range from 20-25 degrees Celsius  Others range from 40-50 degrees Celsius  Hot during the Day and Cold at Night

4. Examples: Cactus and Shrubs http://media-cdn.tripadvisor.com/media/photo- s/01/0e/24/2e/cactus.jpg http://www.public-domain- image.com/plants/flowers/slides/prickly-pear-cactus-in- texas.jpg http://www.texaswildflowerpictures.com/wildflowers/mesquite.jpg Prickly Pear Turpentine bush

5. Plant Adaptations: MUST CONSERVE ENERGY AND WATER LOSS!  Small leaves- less evaporation  Hairy leaves- reduces evaporation and keeps in moisture  Very shallow branching roots to absorb surface water  Live close to ground- water won’t need to travel up as far.  Spikes or thorns prevent animals from eating them for their stored water.  Stomata only open at night  Stomata- opening on plants leaves that allows CO2 in for photosynthesis.

6. Examples: Rodents, Snakes, Lizards, Birds http://www.californiaherps.com/lizards/images/hssustonguerbaz.jpg http://www.americansouthwest.net/arizona/photographs700/d esert-tortoise.jpg http://www.thedailygreen.com/cm/thedailygreen/images/Eh/tdg-pronghorn-de.jpg

7. Animal Adaptations  Store water in fatty tissues  Reduce activity during the day  Nocturnal - Hunt at night  Burrow under ground during the day (Kangaroo Rat)  Specialized kidneys that redirect water back into blood stream.  Exoskeleton or scales reduce water loss.

9. Grasslands

10. Two Types of Grasslands Savanna - Tropical Climate, warmer and closer to the Equator Prairie - Temperate Climate, milder and found in the United States Moderate Rainfall – 50 to 90 cm per year (enough to support grasses but not forests) Very Fertile Soils! – Bread Basket of the World

15. 2 Seasons: Wet Season and …

16. Dry Season

17. Grasslands  Two distinct seasons- Wet and Dry Averages around 60 inches of rain per year but six months with hardly any rainfall. Dry season increases chances of wild fires!

18. Examples: Grasses, Wildflowers and Small Trees http://www.biolib.cz/IMG/GAL/46007.jpg http://www.earthpeace.com/images/Elep hantGrass.jpg Elephant Grass Gum Tree Kangaroo Paw

19. Deep, spread out roots allow grass to get water even in drought. Grass grows from the base- so even if eaten at the tops, they stay alive and still grow.

20. Thin, vertical leaves, lose less water thru evaporation

21.  No low branches to keep leaves away from fire

22. Some animals have adapted to reach those tall branches

23. Animals of The Savannah Examples: Lion, Hyena, Zebra, Gazelle http://misc.qti.com/staff/greg/img/photos/emu.jpg http://lh4.ggpht.com/_nbfHbMxrVCQ/SWtgDikWntI/AAAAAAAAD0Y/YvURvT6qf KY/Wild-Dog-Puppy-2.jpg http://upload.wikimedia.org/wikipedia/commons /8/83/Zebra_Botswana_edit02.jpg

25. Graze in herds- decrease your chances of being the prey Stripes add to camouflage

26.  Prairie dogs and other small mammals burrow to avoid dry windy conditions or predators

27. Specialized Teeth for Grazing

28.  Muscular bodies, strong legs, and tough hooves for running long distances

29. Camouflage – for ambushing prey
