CHAPTER 6: BIOMES 1 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.

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

PRECIPITATION. 3 LATITUDE VS. ALTITUDE LATITUDE ALTITUDE THE DISTANCE THE HEIGHT OF AN

NORTH OR SOUTH OF THE EQUATOR MEASURED IN DEGREES. OBJECT ABOVE SEA LEVEL. 4 END OF 6.1: TIME FOR READING QUIZ

5 SECTION 6.2: FOREST BIOMES 6 TROPICAL RAIN FOREST LOCATED ON OR NEAR EQUATOR WARM YEAR ROUND

LOTS OF PRECIPITATION MOST BIODIVERSITY OF ANY BIOME SOIL IS NOT NUTRIENT RICH 7 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. 8 THREATS TO THE

RAINFOREST HABITAT DESTRUCTION TRADING OF EXOTIC PLANTS AND ANIMALS 9 TEMPERATE RAIN FOREST

LARGE AMOUNT OF RAINFALL HIGH HUMIDITY MODERATE TEMPERATURES LOCATED IN PACIFIC NORTHWEST 10 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 11 TAIGA LOCATED JUST

BELOW THE ARCTIC CIRCLE LONG WINTERS LITTLE PRECIPITATION ACIDIC SOIL CONIFEROUS TREES ANIMALS MIGRATE AND USE CAMOUFLAGE AS

GRASSLANDS TROPICAL GRASSLANDS TEMPERATE GRASSLANDS SAVANNAS OF PRAIRIES IN U.S. MOSTLY GRASSES AFRICA

HAVE WET AND DRY SEASONS PLANTS AND ANIMALS HAVE ADAPTATIONS BASED ON THESE SEASONS WHERE WE GROW OUR CROPS FERTILE SOIL GRAZING ANIMALS

15 THREATS TO THE TEMPERATE GRASSLANDS FARMING LEADS TO SOIL EROSION OVERGRAZING ALSO LEADS TO SOIL EROSION

16 CHAPARRAL TEMPERATE WOODLAND BIOME MEDITERRANEAN CLIMATE PLANTS HAVE SMALL LEATHERY LEAVES. PLANTS ARE

ADAPTED TO FIRE ANIMALS USE CAMOUFLAGE. 17 DESERT RECEIVE VERY LITTLE RAIN VERY HOT DURING DAY BUT COLD AT NIGHT PLANTS CONSERVE

WATER ANIMALS RETAIN WATER AND BURROW IN GROUND 18 TUNDRA NORTHERN ARCTIC PERMAFROST THIN SOIL PLANTS HAVE WIDE,

SHALLOW ROOTS GROW CLOSE TO GROUND ANIMALS MIGRATE OTHERS ARE WELL INSULATED AND USE CAMOUFLAGE 19 THREATS TO THE TUNDRA OIL EXPLORATION POLLUTION DISRUPTING THE SIMPLE FOOD CHAINS
