Intro to Ecology


Intro to ecology

  • 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


Angle of light intensity what s the effect on climate

Angle of Light Intensity – what’s the effect on climate?

Water Moderating Effects


Intro to ecology

  • 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
