Presentation Transcript

  1. Chapter 50 Intro to Ecology

  2. 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

  3. Levels of Ecological Organization • Population • Community • Ecosystem • Biosphere • Atmosphere • Ecosphere • Hydrosphere • Lithosphere

  4. Biomes • Large areas (ecosystems) of the earth with typical types of organisms • They are determined primarily by temp & water availability

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

  6. Seasonal Changes

  7. Precipitation Patterns

  8. Wind Patterns

  9. Water Moderating Effects

  10. 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

  11. Rainshadow Effect

  12. Biomes • Tundra • Taiga • Temperature Deciduous Forest • Grassland • Desert • Chaparral • Tropical Rainforest • Estuary • Coral Reef
