What Are Biomes

  1. 1. What are biomes? The biosphere is divided into major areas called biomes .
  2. 2. BIOMES <ul><li>A biome is determined mainly by its climate-like temperature and rainfall. </li></ul><ul><li>Each biome has a different climate, which, in turn, affects the soil. </li></ul><ul><li>The earth’s land areas are divided into 6 major biomes. </li></ul>
  3. 3. 1. TUNDRA <ul><li>Bitterly cold and covered with snow and ice. </li></ul><ul><li>Ground remains permanently frozen (permafrost). </li></ul><ul><li>Only certain small plants such as mosses and grasses can grow. </li></ul><ul><li>Some animals like reindeer and foxes move in during the growing season. </li></ul>
  4. 4. Tundra
  5. 5. 2. CONIFEROUS FOREST <ul><li>Confers = cone-bearing trees (pines, fir) </li></ul><ul><li>Cold climate </li></ul><ul><li>Dense forests (tree tops block out a lot of sunlight) </li></ul><ul><li>Grasses, small trees cannot grow – only some shrubs, ferns and mosses thrive. </li></ul><ul><li>Animals such as squirrels, moose, birds, and insects live here. </li></ul>
  6. 7. 3. DECIDUOUS FOREST <ul><li>Maples and oaks – shed leaves in Fall. </li></ul><ul><li>Thrive in moderate climates. </li></ul><ul><li>Summers may be hot and winters may be cold. </li></ul><ul><li>Receive a good supply of water. </li></ul><ul><li>Dense forests </li></ul><ul><li>Provides habitats for many animals. </li></ul>
  7. 8. Deciduous forest in Winter
  8. 9. Deciduous forest in Spring
  9. 10. Deciduous forest in Fall
  10. 11. 4. TROPICAL RAIN FOREST <ul><li>Very warm and very moist all the time. </li></ul><ul><li>Receives plenty of sunlight and rain. </li></ul><ul><li>Excellent for plant growth and soil development. </li></ul><ul><li>Plants grow thick and tall. </li></ul><ul><li>Found in areas near the equator. </li></ul><ul><li>Support more plant life and animal species than any other biome. </li></ul>
  11. 13. 5. GRASSLANDS <ul><li>Mostly grass! </li></ul><ul><li>Temperatures similar to deciduous forest. </li></ul><ul><li>Do not receive much rainfall – enough rain to support grasses but not trees. </li></ul><ul><li>Excellent for grazing animals. </li></ul><ul><li>Soil is very rich. </li></ul><ul><li>Wheat and corn grow here. </li></ul><ul><li>Home for many small, burrowing animals. </li></ul>
  12. 15. 6. DESERT <ul><li>Very dry; receives very little rainfall. </li></ul><ul><li>Very hot during the day, cold at night. </li></ul><ul><li>Soil is very dry and poor. </li></ul><ul><li>Only a few kinds of plants grow in the desert. </li></ul><ul><li>Very few animals can survive in the desert. </li></ul>
