  1. Intro to Biomes TROPICAL RAIN FOREST SAVANNA TEMPERATE DECIDUOUS FORESTTAIGA TEMPERATE GRASSLANDS DESERT TUNDRA

  2. Tropical Rain Forest Home to more species than all other biomes combined Located in parts of South and Central America, Southeast Asia, parts of Africa, Southern India, and Northeastern Australia

  3. Tropical Rain Forest Organisms Dominant Plants Rainforest Orchid • Broad leaved evergreen trees • Ferns • Large woody vines • Climbing plants • Orchids • Bromeliads

  4. Tropical Rainforest Organisms Dominant Wildlife • Insects • Butterflies • Ants • Beetles • Freshwater fishes • Piranhas • Reptiles • Caymans • Boa constrictors • anacondas • Herbivores • Sloths • Tapirs • Capybaras • Predators • Jaguars • Anteaters • Monkeys • Birds • Toucans • Parrots • Parakeets

  5. Savanna Characterized by a cover of grasses, isolated trees, small groves of shrubs Compact soils, frequent fires, and large animal action Located in large parts of eastern Africa, southern Brazil, and northern Australia

  6. Savanna Organisms Dominant Plants Cycas • Tall, perennial grasses • Trees or shrubs • Drought-tolerant • Fire-resistant

  7. Savanna Organisms Dominant Wildlife • Predators • Lions • Leopards • Cheetahs • Hyenas • Jackals • Aardvarks • Baboons • Insects • termites • Herbivores • Elephants • Giraffes • Antelopes • Zebras • Birds • Eagles • Ostriches • Weaver birds • Storks

  8. Temperate Deciduous Forest Cold winters halt plant growth for several months Trees shed their leaves in Autumn Spring new plants grow Fertile soils rich in humus Eastern U.S. southeastern Canada, most of Europe, parts of Japan, China, and Australia

  9. Temperate Deciduous ForestOrganisms Dominant Plants Maple Leaves • Broadleaf deciduous trees • Some conifers • Flowering shrubs • Herbs • Ground layer • Mosses • ferns

  10. Temperate Deciduous Forest Organisms Dominant Wildlife • Deer • Black bears • Bobcats • Nut and acorn feeders • Squirrels • Omnivores • Raccoons • Skunks • Numerous songbirds • Turkeys

  11. Taiga Largest biome in the world Winters very cold with snow Summer warm, rainy, humid Coniferous trees a.k.a. boreal forest Eurasia and North America

  12. Taiga Organisms Dominant Plants Fir Tree • Needle-leaf coniferous trees • Spruce • Fir • Broadleaf deciduous trees • Berry-bearing shrubs

  13. Taiga Organisms Dominate Wildlife • Predators • Lynxes • Timber wolves • Weasels • Small herbivorous mammals • Large herbivores • Moose • Beavers • Songbirds • Migratory birds

  14. Temperate Grasslands Mix of grasses & fertile soils Plains, prairies Periodic fires Heavy herbivore grazing Central Asia, North America, Australia, Central Europe

  15. Temperate Grassland Organisms Dominant Plants Perennial Grasses • Lush • Perennial grasses and herbs • Resistant to • Drought • Fire • cold
