Biomes ppt

  1. 1. Walk Thru The Biomesand Ecology Part 2
  2. 2. 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
  3. 3. 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:
  4. 4. What You Need To Find For Each Biome:Temp:Precipitation:Soil:Plants:Animals:Human Impact/degradation:Other Facts:
  5. 5. Tropical Rainforest Canopy: dense covering of tree tops Understory: 2nd story of shorter trees and vines under the canopy Fern Gully/Medicine Man
  6. 6. Tropical Dry Forest  Deciduous trees: broad leaves that fall  Wet/Dry season  “Jungle Book” forest
  7. 7. 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”
  8. 8. 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
  9. 9. 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
  10. 10. TemperateWoodland/Shrubland/Chaparral  Dense shrubs  Mediterranean, California coast  Brush fires
  11. 11. Temperate Grassland prairies Midwest (Kansas, Oklahoma, Missouri) Brush fires Think movie “Twister” “Wizard of Oz” and “Little House on the Prairie”
  12. 12. 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”
  13. 13. Northwestern Coniferous “Rainforest” of the temperate climate zone…very DIVERSE vegetation Mild, moist temperatures Think “Twilight” “New Moon” “Eclipse”
  14. 14. 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
  15. 15. Tundra Permafrost: layer of permanently frozen subsoil “Ice Age”
  16. 16. 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
