Using light microscopy, you examine the soil samples and the "goo" from the degraded polyurethane, will this approach allow you to observed all microorganisms present in the samples? why or why not? what are the limitations of this approach?

This approach will not allow you to observe all of the microorganism present in the samples. This is because you cannot look at the soil as a whole you just take some part of it that may contain some organisms while some may not be present in that sample.
