Ch. 50 Ecology 1. Ecology is the study of organismal relationships with their environments 2. The central goal of ecology is 3. The different areas of study are organismal ecology (study of how organisms interact with their environment), population ecology (study of how many different organisms in one particular area interact with their environment), community ecology (study of how many different species in one particular area interact with their environment), and ecosystem ecology (study of how all the organisms in a particular area interact with the abiotic factors). 4. Abiotic-nonliving components of an environment. Biotic-living components of an environment. 5. Climate-the long-term weather conditions for a particular region. Weather- short-term changes in temperature, precipitation, or conditions for a particular area. 6. The tropics are warm because they are located on/around the equator and receive direct sunlight year- round, based on this location. 7. Heat moves in cells and currents around the globe. The Hadley Cell and the Ferrel Cell do this. Hadley Cell is located at the equator and the Ferrel Cell is located above the Hadley. 8. When air moves, hot air rises, cool air sinks. When hot air rises, it swells and absorbs precipitation and when cool air sinks, it condenses and releases the precipitation that it contains. 9. Hadley Cell- located at the equator, reason for why the tropics are so wet and the deserts are so dry.
