Compare | Compare the numbers of microbes obtained by both methods of enumeration (Culture independent and Culture dependent) In your notebook, write out the numbers for both enumeration methods with no decimals or exponents. Contrast the two counts that, in theory, should be the same since we are using two methods to figure out the same thing: how many microbes per gram comprise your soil community. Both answers provide evidence for one of our investigative goals: abundance or microorganisms in your soil community. What does it mean if your two experimental methods don't give the same answer? | ||
Consider the relative insignificance of one gram of anything and the enormity of the number of microbes that thrive in a gram of soil! How is it possible that each of the microbial members of such a soil community can find a niche, obtain all the nutrients needed to grow and reproduce, and contribute to overall health of the soil and to the community of microorganisms? <BR> | |||
