What is a Biome? Biome: A group of land ecosystems with similar climates and organisms. Ecosystem: The community of organisms that live in a particular area, along with their nonliving surroundings.
How many biomes are there and what are they? There are 6 major biomes Rain Forests Desert Grassland Deciduous forest Boreal forest Tundra
Rain Forest Biome Two types: Temperate Rain Forests found in the Northwestern United States. Tropical Rain Forests found along the equator. Sometimes called Jungles.
Temperate Rain Forest Over 300cm of rain per year Huge hardwood trees Moderate temperatures http://www.google.com/imgres?q=temperate+rainforest&um=1&hl=en&sa=N&tbo=d&biw=1280&bih=685&tbm=isch&tbnid=9XlKJdokTeYpnM:&imgrefurl=http://www.treehugger.com/natural-sciences/restoring-ecosystems-biggest-untapped-ally-in-fighting-climate-change.html&docid=XvqCaTCx6AwFLM&imgurl=http://media.treehugger.com/assets/images/2011/10/20090908-temperate-rainforest.jpg&w=468&h=310&ei=zKupUM2INsK_0AGSroHIAQ&zoom=1&iact=hc&vpx=427&vpy=203&dur=1437&hovh=183&hovw=276&tx=157&ty=67&sig=112307318176664303917&page=2&tbnh=145&tbnw=232&start=19&ndsp=24&ved=1t:429,r:27,s:0,i:224 http://www.google.com/imgres?q=temperate+rainforest&um=1&hl=en&sa=N&tbo=d&biw=1280&bih=685&tbm=isch&tbnid=gJBks9swq96VzM:&imgrefurl=http://www.garthlenz.com/contents/Travel/image-lenz-wwf-52/&docid=AOD_oAL0_VMB5M&imgurl=http://cdn.lightgalleries.net/4bd5ec0174be3/images/lenz-wwf-52-2.jpg&w=1000&h=799&ei=zKupUM2INsK_0AGSroHIAQ&zoom=1&iact=hc&vpx=443&vpy=190&dur=1543&hovh=201&hovw=251&tx=131&ty=73&sig=112307318176664303917&page=3&tbnh=145&tbnw=189&start=43&ndsp=31&ved=1t:429,r:45,s:0,i:278
Tropical Rain Forest Close to the equator. Climate is warm and humid year round Several distinct tree layers in the tropical forest. Have more plant and animal species than any other biome! http://t0.gstatic.com/images?q=tbn:ANd9GcSeu8KuVlbFzwZibBj_scueQv-QKUlnSYNlUzivlaYWNAvYJoOH http://t2.gstatic.com/images?q=tbn:ANd9GcRPS_gjYdvF7Ohafofbgm2T9v0yMgUqgXRQWaNg7wm7oS21CIzX
Desert Biome Less than 25cm of rain per year. Evaporation exceeds precipitation. Large shifts in temperature from night to day. Located just outside of the equatorial regions. Organisms need special adaptations to survive. http://t1.gstatic.com/images?q=tbn:ANd9GcSrLZE3UYzwXJjzbdNOwDXpqUgQrT5X1SNhWM41dXCIAzZ8piwd5g http://t2.gstatic.com/images?q=tbn:ANd9GcSRj9b63KsXJVCRqpmRWxAGe9eM5o9phHCmoolLcjjK7JjRcU8TKQ
Grassland Biome Middle Latitudes Prairie: An area populated mostly by grasses and other non-woody plants. 25-75cm of rain per year. Savanna: up to 120cm of rain per year. Has grasses and small shrubs and small trees. Home to largest animals on Earth. http://upload.wikimedia.org/wikipedia/commons/thumb/5/57/Cumulus_Clouds_over_Yellow_Prairie2.jpg/300px-Cumulus_Clouds_over_Yellow_Prairie2.jpg http://room42.wikispaces.com/file/view/savanna_2.jpg/33513641/savanna_2.jpg
Deciduous Forest Biomes Deciduous trees loose their leaves and grow new ones annually. About 50cm per year. Large variation in temperatures over the year. http://t3.gstatic.com/images?q=tbn:ANd9GcQ8fMIUjMQojX6cutzXrrJ5OTeT_Xee65NVfiQPgnVSuuU28b2p_w http://t2.gstatic.com/images?q=tbn:ANd9GcTkkB6jUw1-b13HfMQi8uR87QrgIoCtKVmjJiZzqC0In47CkBmlaQ
Boreal Forest Biomes Also known by its Russian name: Taiga Located in colder regions in the upper middle latitudes Trees are coniferous. Seeds are in cones and leaves are needle shaped. http://cgf3m-2albertaoilsands.wikispaces.com/file/view/Boreal_Forest.jpg/207145204/Boreal_Forest.jpg http://cdn2.planetminecraft.com/files/resource_media/screenshot/1218/scotch-pine-cone-marilynne-bull_2174706.jpg
Tundra Biome Extremely dry and cold Soil is frozen year round and is called permafrost Plants include mosses, grasses, shrubs and some dwarf variety of trees. Shallow ponds and marshy areas in the summer. Only located in the Northern Hemisphere and north of the Arctic Circle. http://www.marietta.edu/~biol/biomes/images/tundra/alaskatundra3.jpg
