2.  A biome is a large geographic area with a characteristic climate. A biome consists of several communities / ecosystems. Part of the earth that has more or less the same kind of abiotic and biotic factors spread over a large area thus creating a typical ecosystem over that area.  Biomes can be classified as terrestrial or aquatic.

3.  Desert  Tundra  Grassland (shrubland)  Forest  Deciduous Forest  Rainforest  Taiga (Boreal forests)

4.  Found in Northern Hemisphere  Very short growing season  Permafrost restricts root growth  Reason why has only small plants  Plants  Mosses, lichens, no trees  Animals  Lemmings, arctic fox, snowy owl, caribou

5.  Grass  Threat = agriculture, manmade fires  Plants  Grazing adapted  Woody plants, trees and shrubs  Animals  Bison, giraffe, prairie dogs

6.  Sand and low precipitation  Plants  Drought and salt resistant  Spiny and succulent (cactus)  Animals  Kangaroo rat, lizards

7.  High northern latitudes below Tundra  Largest terrestrial biome  Plants  Evergreens, conifers (spruce, fir and pine)  Short roots, cone shape  Animals  Moose, lynx, Snowshoe hare

8.  Rich soils = productive area  Trees lose leaves every year  Can keep water in winter  Plants  Broadleaf are seasonal  Maple, Oak  Animals  Deer, Blackbear

9.  High rainfall  Divided into layers  Rapid decomposition gives nutrients to plants  Plants  Animals

10.  Saltwater  Freshwater

11.  Oceans, some lakes and marshlands  Abiotic factors: waters and sunlight  Plants  Kelp  Eeelgrass  Animals  Sea otters ▪ Coat and kelp leaves  orca (killer whale) ▪ Colors blend into ocean (dark top and light bottom)

12.  Feshwater (slow flowing rivers, lakes and ponds)  Wetlands (Bogs, swamps, and marshland)  Video: Aliant learning- Habitats and Biomes: Ecosystems of the World
