Ecology – study of the relationship between organisms and their living and nonliving environment

    • Biotic factors – living factors
      • Predators, prey, competitors, parasites, mutualism, etc
    • Abiotic factors – nonliving factors
      • Precipitation, soil type/rocks, temperature, wind, sunlight, altitude
levels of ecological organization
Levels of Ecological Organization
  • Population
  • Community
  • Ecosystem
  • Biosphere
    • Atmosphere
    • Ecosphere
    • Hydrosphere
    • Lithosphere
biomes
Biomes
  • Large areas (ecosystems) of the earth with typical types of organisms
  • They are determined primarily by temp & water availability

Ocean currents can make areas near them warmer or colder than other parts of the world at same latitude

  • Rainshadow effect
    • Moist air from ocean rises up the mountains and cools – rain falls
    • Drier air then passes over the mountains and warms as it falls – absorbing moisture
    • Areas inland from the mountains are drier – (rainshadow) – lack of rain
