intro to ecology
  1. Organismal ecology
    1. Population ecology
      1. Community ecology
        1. what determines the distribution and abundance of organism?
          1. abiotic factors
            1. temperature, precipitation, soil etc
              1. global climate patterns
                1. temperature
                  1. equator is hot; poles is cold
                  2. precipitation
