1.2 Terrestrial Biomes

Biome

area that shares a combination of average, yearly temperature and precipitation

tundra/boreal

biomes found at high latitudes

Temperate

biome found at middle latitudes

tropical

biomes found at the equator

latitude

_ determines temperature and precipitation, which is why biomes exist in predictable pattern

soil nutrients

availability of _ determines which plants can survive in a biome

Tropical rainforest

nutrient-poor soil because of high plant competition

Boreal forest

nutrient-poor soil because of low temperature and low decomposition rate of dead organic matter

temperate forest

nutrient-rich soil with lots of dead organic matter, leaves, and warm temperature/moisture for decomposition

climate change

causes a shift of the location of biomes on earth
