Biomes Terrestrial ecosystems that cover a large region of Earth Characterized by communities of plants and other organisms adapted to the climate and other abiotic factors
Major Terrestrial Biomes Temperate Woodland/shrubland Tropical Rainforest (Chaparral) Tropical Dry Forest Temperate forest Tropical Savannah Northwestern Coniferous Desert Boreal Forest/Taiga Temperate Grasslands (Prairie) TundraWhat You Need To Find For Each Biome:Temp:Precipitation:Soil:Plants:Animals:Human Impact/degradation:Other Facts:
What You Need To Find For Each Biome:Temp:Precipitation:Soil:Plants:Animals:Human Impact/degradation:Other Facts:
Tropical Rainforest Canopy: dense covering of tree tops Understory: 2nd story of shorter trees and vines under the canopy Fern Gully/Medicine Man
Tropical Dry Forest Deciduous trees: broad leaves that fall Wet/Dry season “Jungle Book” forest
Tropical Savannah In the tropics Wet/dry season Large mammals keep large trees from growing in Less rainfall than tropical Dry forest Organisms ADAPT to fires during dry season Think “Lion King”
Desert Around 25-35o Latitude N and S Hot Days and Cold Nights Plants and animal adaptations Spines, waxy cuticles, scales Think “The Mummy” and “The Sahara” Rain shadow effect
Rain shadowEffect Warm air on coast rises rapidly because of mountain “Orographic lifting” Lots of precipitation on one side=lush vegetation Other side very dry air=desert like conditions
Temperate Grassland prairies Midwest (Kansas, Oklahoma, Missouri) Brush fires Think movie “Twister” “Wizard of Oz” and “Little House on the Prairie”
Temperate Forest Mix of coniferous and deciduous trees Humus (HUE-Mus) material formed from decaying leaves….very fertile!!! Forests with leaves that change colors Think fairy tale forest “Snow White” and “Sleeping Beauty”
Northwestern Coniferous “Rainforest” of the temperate climate zone…very DIVERSE vegetation Mild, moist temperatures Think “Twilight” “New Moon” “Eclipse”
Boreal Forest/ Taiga Bitter cold winters Coniferous trees Make the timberline…border between taiga and the tundra…LINE of TREES Think “X-Men Origins”…Wolverine’s home
Tundra Permafrost: layer of permanently frozen subsoil “Ice Age”
Other interestingecosystems… Mountain Ranges On all continents Abiotic and biotic factors change with ELAVATION (as u go up) Therefore plants and animals change VERTICALLY Grassland at base woodland/pines spruce/conifer forest tundra like open area at summit with wildflowers Polar Ice Caps Border the Tundra Cold year round Characterized by ice and snow Plants and algae are few but include Mosses and Lichens North Pole Sea ice and ice cap that covers Greenland Polar bears, seals, insects and mites South Pole 5 km thick layer of ice Penguins and marine mammals
