The World’s Biomes

What is a Biome? Areas of the Earth that are defined by: Climate Geography Precipitation Vegetation Species variety

Tropical Rainforest Dense vegetation Wide variety of species Tall trees Little light reaches forest floor Hot, humid climate Rainfall: 155 in./yr. Temp: 34°C

Grassland Also called prairies or plains Wide variety of grasses Limited variety of species because of protection Rainfall: 20 in./yr. Temp: 30°C

Desert Rainfall: less than 10 in./yr. Temp: 38°C Very limited species and vegetation variety Cacti and reptiles

Deciduous Forest Hardwood trees, that shed their leaves in autumn (Why?) Four distinct seasons A fair variety of species Rainfall: 40 in./yr. Average temp: 28°C

Tundra Permafrost Extremely cold winter climate Very little vegetation Limited species variety Rainfall: 15 in./yr. Temp: 12°C – (-26°C) Alpine: above tree line of very high mts.

Coniferous Forest (taiga) Coniferous trees Fairly limited variety of plants and animals Cold winters, warm summers Wet climate all year round Rainfall: 23 in/yr Temp: 14°C

Savanna Dry winters, wet summers Warm temps, but not extremely hot Limited plant and vegetation variety Good species variety Rainfall: 59 in./yr. Temp: 25°C
