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

4. A.k.a Tiaga 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. 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. 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. 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. Combo of grassland and small groups of trees Located in Africa Acacia trees along with giraffes, wildebeast, lions, hyenas, and gazelle

9. 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
