    • Quadrat
      • place a 1m squared on the ground at a random point
      • count all organisms within the quadrant
      • repeat steps 1 and 2 as many times as you can
      • work out the mean number of organisms
      • repeat steps 1-4 in the second sample area
      • finally compare the two means
    • population size
      • mean number of organisms per m squared
    • environmental factors
      • temperature
      • availability of water
      • availability of oxygen and carbon dioxide
      • availability of nutrients
      • amount of light
