  1. Section 15-3, 15-4 and 15-5“Biomes”

  2. Because we can’t take a trip around the world, I’m trying to give you a visual of all the diverse places on Earth

  3. 15.3 KEY CONCEPT :Biomes are land-based, global communities of organisms.

  4. Earth has six major biomes.

  5. Source: World Meteorological Organization • Tropical rain forest biomes produce lush forests. • warm temperature • abundant precipitation all year • soil poor in nutrients • vast diversity

  6. Quick Trip To South America…. • http://www.youtube.com/watch?v=B1_FO5-2P1Y

  7. Grassland biomes are where the primary plant life is grass. • median temperature • median precipitation all year • soil poor in nutrients • high diversity

  8. Boom Dee Addah…. • http://www.youtube.com/watch?v=RmUK3tMsp6Y

  9. Tucson, Arizona Source: National Oceanic Atmospheric Administration • Desert biomes are characterized by a very arid (dry) climate. • extreme temperatures • soil with little organic matter • high diversity

  10. Interested in purchasing some property? • http://www.youtube.com/watch?v=FPnkvJ7qmVI

  11. Temperate forest biomes include deciduous forests and rain forests. • hot summers and cold winters • very fertile soil • very diverse

  12. Let’s Go to New England… • http://www.youtube.com/watch?v=woYUntbc87A

  13. Banff, Canada Source: Environment Canada • The taiga biome is located in cooler northern climates. • long winters and short summers • small amount of precipitation • soil is thin and poor in nutrients • mostly evergreens

  14. Brrr…It’s cold in here! • http://www.youtube.com/watch?v=_Vxh8MzvFBw

  15. Barrow, Alaska Source: National Oceanic Atmospheric Administration • The tundra biome is found in the far northern latitudes with long winters. • winter lasts 10 months • limited precipitation • permafrost • very low diversity

  16. Something’s frozen around here… • http://www.youtube.com/watch?v=6LO1QSuHlsY

  17. 15.3 KEY CONCEPT :Marine ecosystems are global.

  18. Coastal waters contain unique habitats. • Coral reefs are found in warm waters. • tropical climate zone • great amount of biomass

  19. Wow… does stuff really come in that color? • http://www.youtube.com/watch?v=_syVb8jZu4Y

  20. Kelp forests are found in cold, nutrient-rich waters. • large communities of seaweed • great amount of biomass

  21. 15.5 KEY CONCEPT: Freshwater ecosystems include estuaries as well as flowing and standing water.

  22. An estuary is a partially enclosed body of water. • mixture of fresh water with salt water • tons of biodiversity

  23. Freshwater ecosystems include moving and standing water.

  24. Wetlands are among the most productive ecosystems. • provide a home for many species • filter dirty water • renew underground water supply
