- For Mycobacterium tuberculosis In this part, you will describe how the microbe interacts with other organisms and/or the non-living environment. Choose the most pertinent interactions for your microbe. For example, if your microbe is a human pathogen, focus on the interaction with human cells and the immune system. If your microbe is a nitrogen-fixer, focus on the interaction with other organisms via the nitrogen cycle. aim for including at least 5 key points regarding the interactions and describe those points in detail please write a new heading for each of your key points so that it's clear to me what the 5 points arearrow_forwardHow do microbes differ in their response to oxygen levels?
