Transcript

  • 1. Exploring Ecosystems What is an ecosystem?
  • 2. These region are called biomes. Some of these areas would be prairies, tropical rainforests, and deserts.
  • 3. Abiotic Factors Abiotic or non-living factors are important to biotic or living species. Some abiotic factors are elevation, nutrients, rainfall, rocks, slope, aspect to the sun, soil, temperature, and wind.
  • 4. This area might be high above timberline in the mountains of Colorado. Some abiotic influences might be altitude, clouds, rocks, and soil.
  • 5. Biotic factors  Living things- plants,, animals, microbes etc.
  • 6. Garden of the Gods is a city park near the base of Pikes Peak. From here we can see four of the five life zones (ecosystems) of Colorado’s Front Range ecology; foothills, montane, sub-alpine, and alpine.
  • 7. The plains are the fifth life zone found on the front range in Colorado.
  • 8. Subalpine Alpine Montane Foothills Plains
  • 9. High elevations Colder T temperature decreases 3 degrees he per 1000-foot rise) Shorter frost-free season (6 weeks) Snow possible any month More rain/snow Average 40 inches in the Colorado alpine.
  • 10. Low elevation Warmer Longer frost-free season Colorado S prings - 21 weeks Less Rain/snow (average in Colorado Springs is 15.4 inches)
  • 11. Ecologica l cha nges due to increa sing eleva tion a re simila r to those ca used by increa sing la titude. A trip up Pikes Pea k is like a trip to the Arctic tundra , except the Arctic ha s extreme sea sona l differences in da ylight, a nd the a lpine receives more intense sunlight.
  • 12. As elevation changes, life zones and climates change.
