  1. Biomes

  2. What is a Biome? • Biome = region characterized by distinct plant and animal populations along with similar abiotic conditions. • Change by latitude • Ocean biomes = marine habitats • Land biomes = terrestrial habitats

  3. Tundra • Northern most biome • Treeless permafrost • Short growing seasons • Least rainfall of all biomes • Moss, lichens, caribou, arctic fox, wolves, and lemmings

  4. Coniferous Forest • A.k.aTiaga or Boreal Forest • Populated by evergreen trees (pine, spruce, fir) • Deer, moose, and elk populations • 15-30 in. of rainfall per year • Avg. temperature 14°F (Winter) and 57°F (Summer)

  5. Temperate Deciduous Forest • Braod-leaved trees (oak, maple, beech, hickory) • Leaves shed yearly before winter • 30-60 in. rainfall yearly • Avg. temperature is around 50°F • Animals include: deer, squirrels, beavers, and bears

  6. Tropical Rain Forest • Most yearly rainfall totals (up to 260 in./year); no seasonal change • Produce 40% of Earth’s oxygen • Average temperature between 68-93 °F • Most biodiversity on planet located in these biomes (i.e. epiphytes) • ¼ of all medications come from rainforests

  7. Grassland (Prairie) • Often destroyed by humans for crops • Soil rich in nutrients • Low rainfall (10-30 inches/year) • Antelope, prairie dogs, bison, coyotes • Tall grasses and very little tree cover

  8. Savannah • Combo of grassland and small groups of trees • Located in Africa • Acacia trees along with giraffes, wildebeast, lions, hyenas, and gazelle

  9. Desert • Low rainfall (under 15 cm a year on average) • Temperature average is 64 °F but may reach over 100 °F during daylight hours • Shrubs, cactus (adapted to low water availability) • Jack rabbits, snakes, and lizards
