1. CHAPTER 6: BIOMES

2. SECTION 6.1 WHAT IS A BIOME?
A BIOME IS A LARGE REGION CHARACTERIZED BY TWO FACTORS: CLIMATE AND PLANT LIFE.
CLIMATE IS THE WEATHER CONDITIONS (TEMPERATURE AND PRECIPITATION) IN AN AREA OVER A LONG PERIOD OF TIME.

3. PLANT LIFE
THE TWO MAIN FACTORS THAT DETERMINES WHAT TYPE OF PLANTS GROW IN A BIOME ARE TEMPERATURE AND PRECIPITATION.

4. LATITUDE VS. ALTITUDE LATITUDE ALTITUDE
THE DISTANCE NORTH OR SOUTH OF THE EQUATOR MEASURED IN DEGREES.
THE HEIGHT OF AN OBJECT ABOVE SEA LEVEL.

6. SECTION 6.2: FOREST BIOMES

7. TROPICAL RAIN FOREST LOCATED ON OR NEAR EQUATOR WARM YEAR ROUND
LOTS OF PRECIPITATION
MOST BIODIVERSITY OF ANY BIOME
SOIL IS NOT NUTRIENT RICH

8. LAYERS OF THE RAIN FOREST
Emergent layer is on top with direct sunlight = tallest trees
Canopy (lower and upper) has lots of animals, flowers, fruits and epiphytes.
Understory gets very little light so plants adapted to shade live here.

9. THREATS TO THE RAINFOREST
HABITAT DESTRUCTION
TRADING OF EXOTIC PLANTS AND ANIMALS

10. TEMPERATE RAIN FOREST LARGE AMOUNT OF RAINFALL HIGH HUMIDITY
MODERATE TEMPERATURES
LOCATED IN PACIFIC NORTHWEST

11. TEMPERATE DECIDUOUS FOREST
LOCATED ALONG EAST COAST
HAS FOUR SEASONS
MOSTLY DECIDUOUS TREES THAT LOSE LEAVES IN WINTER
PLANTS ARE ADAPTED FOR SEASONAL CHANGES AND ANIMALS ARE ADAPTED TO USE FOREST FOR FOOD AND SHELTER

12. TAIGA LOCATED JUST BELOW THE ARCTIC CIRCLE LONG WINTERS
LITTLE PRECIPITATION
ACIDIC SOIL
CONIFEROUS TREES
ANIMALS MIGRATE AND USE CAMOUFLAGE AS ADAPTATIONS

13. END OF 6.2: TIME FOR READING QUIZ

14. SECTION 6.3: GRASSLAND, DESERT, AND TUNDRA

15. TWO DIFFERENT GRASSLANDS
TROPICAL GRASSLANDS
TEMPERATE GRASSLANDS
SAVANNAS OF AFRICA
HAVE WET AND DRY SEASONS
PLANTS AND ANIMALS HAVE ADAPTATIONS BASED ON THESE SEASONS
PRAIRIES IN U.S.
MOSTLY GRASSES
WHERE WE GROW OUR CROPS
FERTILE SOIL
GRAZING ANIMALS

16. THREATS TO THE TEMPERATE GRASSLANDS
FARMING LEADS TO SOIL EROSION
OVERGRAZING ALSO LEADS TO SOIL EROSION

17. CHAPARRAL TEMPERATE WOODLAND BIOME MEDITERRANEAN CLIMATE
PLANTS HAVE SMALL LEATHERY LEAVES.
PLANTS ARE ADAPTED TO FIRE
ANIMALS USE CAMOUFLAGE.

18. DESERT RECEIVE VERY LITTLE RAIN VERY HOT DURING DAY BUT COLD AT NIGHT
PLANTS CONSERVE WATER
ANIMALS RETAIN WATER AND BURROW IN GROUND

19. TUNDRA NORTHERN ARCTIC PERMAFROST THIN SOIL
PLANTS HAVE WIDE, SHALLOW ROOTS
GROW CLOSE TO GROUND
ANIMALS MIGRATE
OTHERS ARE WELL INSULATED AND USE CAMOUFLAGE

20. THREATS TO THE TUNDRA OIL EXPLORATION POLLUTION
DISRUPTING THE SIMPLE FOOD CHAINS OF THIS VERY FRAGILE BIOME
