  • 1. Which Biome, Where?Comparing Land and Water Environments on Earth
  • 2. Key Objectives: The student will:– Investigate and Understandthe differences betweenecosystems and biomes
  • 3. Key Objectives: The student will:– Differentiate betweenecosystems and biomes
  • 4. Key Objectives: The student will:– Investigate and Understandthe characteristics of land(terrestrial), marine (saltwater) and freshwater biomes
  • 5. Key Objectives: The student will:– Compare and contrast the bioticand abiotic characteristics ofmajor land, marine andfreshwater biomes
  • 6. Key Terms Biome Marine Biome Freshwater Biome Tundra Desert Grassland Dormancy Tropical Rain Forest Taiga (EvergreenForest) Temperate DeciduousForest Hibernation Migration
  • 7. Biome Large geographical regionswith similar climates, plant andanimal life
  • 8. Land Biomes (Terrestrial) Tundra Taiga Temperate DeciduousForest Tropical Rain Forest Grasslands Desert
  • 9. Tundra A terrestrial biome characterizedby its frost-molded landscapes.It is the coldest of all the biomes.
  • 10. Tundra Tundra comes from the Finnishword tunturi, meaning treelessplain
  • 11. Taiga (Evergreen Forest) A terrestrial biome characterizedby forest covered withconiferous trees (Pine Trees).
  • 12. Taiga (Evergreen Forest) The taiga is thelargest terrestrialbiome in theworld. It covers largeparts of Canada,Europe, and Asia.
  • 13. Temperate DeciduousForest More preciselytermed temperatebroadleaf forest
  • 14. Temperate DeciduousForest A terrestrial biomecharacterized by having atemperate climate and thatmost of the trees lose theirleaves in the winter Rich dark soil from years ofleaf decomposition
  • 15. Tropical Rain Forest A terrestrial biome characterizedby its hot, moist environment itis found near Earths equator.
  • 16. Tropical Rain Forest Though only about 6% of theearth’s land surface. It isearths most complex biome interms of both structure andspecies diversity.
  • 17. Desert A terrestrial biome characterizedlittle rainfall and dry barrenlandscapes. It covers about onefifth of the Earths surface
  • 18. Grasslands Covers over 20% of the earth’s surface. Large areas of the North America called theprairie. Also located in central Europe andcentral Asia In Africa it is called the savannah Deep rich soil excellent for farming
  • 19. BREAK
  • 20. Aquatic Biomes The Marine Biome The Freshwater Biome
  • 21. Marine Biome Makes up the largestpercentage of aquatic biomeson earth. These biomes are extremelyimportant to how our earthcurrently functions.
  • 22. Marine Biome These biomes involve a mediumto high percentage of salt in thewater
  • 23. Freshwater Biome An aquatic biome that accountsfor less than one fifth of the areaof the Earth.
  • 24. Freshwater Biome It provides half of the drinkingwater, one third of the waterused for irrigation.
  • 25. Support Terms
  • 26. Hibernation A behavioral adaptation observedin some organisms which live incolder climates where the organismslows down and sleeps out the coldseason
  • 27. Migration The instinctivemovement ofanimals such asbirds movingsouth for thewinter
  • 28. Dormancy The time of year when plants do notappear to be living (brown grass inWinter) When a seed has not yet germinated
  • 29. Adaptation An evolutionary change that allows aspecies to survive in a particularenvironment.– Hummingbirds long beak for extractingnectar– Penguins are flightless birds but usetheir wings to swin
  • 30. Lab TimeNow it is time to introducethe new lab.Pease open your Green labguides to page1Read the introductionsilently as I read it aloud
  • 31. Essential Learnings Regions of the world located atsimilar or opposite latitudesoften have similar climates andecosystems These are called Biomes
  • 32. Essential Learnings There are six (6) terrestrialbiomes– Tundra– Taiga (Evergreen Forest)– Temperate Deciduous Forest– Tropical Rain Forest– Grassland– Desert
  • 33. Essential Learnings There are two (2) aquaticbiomes– Marine– Freshwater
  • 34. Essential Learnings Climate is defined as the typicallong-term weather pattern foundin an area over time
  • 35. Essential Learnings The tilt of the earth on its axiscombined with its revolutionaround the sun play a major rolein the climate of any region
  • 36. Essential Learnings Climate factors:– Precipitation– Temperature– Altitude– Latitude
  • 37. Essential Learnings Climate may also be affected bynearby large bodies of water,high altitude and a “rain shadoweffect” of a mountain range.
  • 38. Essential Learnings Regions of the world located atsimilar or opposite latitudesoften have similar climates andtend to have ecosystems withsimilar dominant plants andanimals
  • 39. Essential Learnings Organisms adapt to theirenvironments Natural Selection is the processwhere the best suitedorganisms for the environmentsurvive and the less suited donot
  • 40. Essential Learnings Adaptations may be:– Structural (physical features)Beak sizeLoss of flight but ability to swim(penguins)
  • 41. Essential Learnings Adaptations may be:– BehavioralHibernationMigration
  • 42. Essential Learnings Many plants go dormantperiods of cold and low sunlightor during the harsh winterseason They come back/revive everyspring.
