1. Unit 15: Terrestrial Biomes Overview

2. biome large geographic areas that have similar climates and ecosystems (the types of organisms that live there)

3. deciduous trees that have flat leaves that change color and fall off before winter

4. climate includes the average yearly temperature and amount of rainfall an area receives

5. coniferous trees with cones and thin, needle-shaped leaves; evergreen trees such as pine, fir, and spruce

6. An ecosystem consists of a biological community and its physical environment. Terrestrial ecosystems include, temperate deciduous forest, temperate grassland, savanna, taiga, tundra, and desert. Marine and freshwater aquatic ecosystems include oceans, lakes, rivers, and wetlands. All of Earth's ecosystems together constitute the biosphere.

14. tropical rain forest A biome with warm temperatures and large amounts of rainfall; most are located near the equator Ferns, orchids, and tall (canopy) trees Parrots, snakes, frogs, monkeys, lizards

24. savanna or tropical grassland a grassland biome near the equator Warm temperatures Wet/dry seasons Grasses, shrubs, and a few small trees Animals like zebras, giraffes, wildebeest, gazelles, lions, leopards

30. LatitudeAverage Temperatures Average Rainfall 15° - 25° N and S 25° C.-49° C. 77° F-120 ° F 0.25 cm (0.1 in) Desert

31. deserts A warm biome that receives less than (10 in.) 25 cm of rain each year Some have cold winters, some have cold nighttime temperatures, but they have high daytime temperatures Creosote bush, saguaro cactus Owls, hawks, roadrunners, rattlesnakes, and lizards

35. LatitudeAverage Temperatures Average Rainfall 30° - 55° N and S (Europe: 45° - 60° N) 31 °C (56 ° F) 81 cm (32 in) Temperate Deciduous Forest

36. temperate deciduous forest A biome with trees that lose their leaves in the fall 4 distinct seasons Rainfall is spread out across the entire year Trees like maple, oak, elm Animals include white-tailed deer, raccoons, foxes and squirrels

37. Temperate Deciduous Forest

39. Temperate Grasslands

43. LatitudeAverage Temperatures Average Rainfall 30° - 55° N and S 31 °C (56 ° F) 81 cm (32 in) Temperate Grasslands

44. temperate grassland A biome found at the same latitude as temperate deciduous forests Covered with grasses, not trees; with rich fertile soil (Great Plains in the US/prairie) Also called pampas, steppe or veldt Grazing animals like antelope, prairie dogs, coyotes, bison/buffalo

45. prairie dog

47. Taiga

49. LatitudeAverage Temperatures Average Rainfall 50° - 70° N and S 41 °C (74 °F), -25 °C to 16 °C (- 14 °F to 60 °F) 31 cm (12 in). Taiga

50. taiga (ty-guh) a cold biome with long winters with a lot of snow Some animals migrate to warmer climates in the winter; some hibernate Plants include evergreen trees such as pine, fir, and spruce (coniferous forests) Animals include moose, bear, wolves and lynx.

51. Tundra

54. LatitudeAverage Temperatures Average Rainfall 60° - 75° N -22 °C to 6 °C (-10 °F to 41 °F) 20 cm (8 in). Tundra

55. tundra a cold biome that does not support trees the largest biome covering about 1/5 of Earth’s land receives little rainfall made up of permafrost—a layer of permanently frozen soil includes mosses, lichens and caribou, arctic foxes and snowshoe hares

56. lichen composed of a fungus in symbiotic union with an alga (protist) have a greenish, gray, yellow, brown, or blackish areas that grow in leaflike, crustlike, or branching forms on rocks, trees, etc.
