Biomes

  1. 1. A biome is a major region that is  characterized by its climate, soil type(s), and the dominant plants, animals, and other organisms that live there.  A biome is made up of many individual ecosystems.
  2. 2. Types of Biomes Tundra   Desert  Grassland  Coniferous forest  Temperate deciduous forest  Tropical rainforest
  3. 3. Is the temperature of each Biome: Hot, moderate, or cold? Tundra -   Desert -  Grassland -  Coniferous forest -  Temperate deciduous forest -  Tropical rainforest -
  4. 4. Is the temperature of each Biome: Hot, moderate, or cold? Tundra - Cold   Desert - Hot  Grassland - Moderate  Coniferous forest - Cold  Temperate deciduous forest - Moderate  Tropical rainforest - Hot
  5. 5. Climate • Weather conditions over a long period of time
  6. 6. Latitude and Altitude Affect the Climate Gets colder the higher up you go  (altitude)  Gets colder the farther north/south of the equator you go (latitude)  Most of food on Earth is grown between 30-60 degrees north and south of the equator  -- Do we live in this latitude??--
  7. 7. Tundra
  8. 8. Tundra Arctic tundra can be found in  Antarctica and the North Pole, North of the Arctic Circle.  Grass, lichen and herbs  Permafrost – layer of soil that is always frozen.  Very short warm season that is very wet  Many insects during warm season
  9. 9. Coniferous Forest
  10. 10. Coniferous forest Is one of the most fragile biomes   Spruce and Fir trees  Found in Northern Hemisphere  Growing season very short  Nearly constant daylight in summer  Many lakes and swamps
  11. 11. Temperate Deciduous Forest
  12. 12. Temperate Deciduous Forest Climate and amount of sunlight can  vary tremendously between each season.  Deciduous trees lose their leaves in fall.
  13. 13. Grassland
  14. 14. Grasslands Grasslands are characterized by their  tall, perennial grasses and lack of trees. 2 Types  1. Tropical grasslands: between the Tropic  of Cancer and the Tropic of Capricorn, hot year-round, very dry, season of heavy rain. 2. Temperate grasslands: north of the  Tropic of Cancer or south of the Tropic of Capricorn, cold winters and hot summers. Cover a quarter of the land on Earth 
  15. 15. Desert • Deserts take up 8.6 million square miles on Earth.
  16. 16. Desert Get less than 25 cm of rain each year   Has little or no vegetation  Driest places on earth  Often located on the dry side of mountain ranges
  17. 17. Tropical Rainforest
  18. 18. Tropical Rainforest Contain over half of the world's plant  and animal species live here. All fit into only 7 percent of the world's land. Found in: Central Africa, Southeast  Asia, Philippines, New Guinea, Central and South
  19. 19. Tropical Rainforest Layers:   Top – Emergent layer – tallest trees above rest of forest  Next – Canopy – top of normal trees  Lower canopy – epiphytes – plants that grow on tree trunks – not soil - because light is so far from ground.  Understory – lowest level, much darker
  20. 20. Climatograms  A climatogram is a graph that shows average monthly values for two factors: temperature and precipitation.  Temperature is expressed in degrees Celsius and is plotted as a smooth curve.  Precipitation values are given in centimeters and are plotted as a histogram.
