In the case file the organism responsible for the patient's death is a normal member of the human microbiota. how do you explain it cause the death of the patient

The patient was immunocompromised or the microbiota moved to an unprotected sites in the patient.

Explanation:

The normal member of the human microbiota can cause disease in immunocompromised individuals or when the microbiota move to an unprotected sites in the body of an individual.

Immunocompromised individuals are those whose immune systems are not fully functional due to reasons such as genetic defects, taking of immunnosuppressive drugs, or infection by immune-targeting pathogens.  

Normal microbiota are known to be opportunistic pathogens that are capable of causing infections when a host becomes immunocompromised or when they moved from their regular habitats to an unprotected site within the body.

For example, Staphylococcus epididermis which happens to be one of the normal microbiota of the skin's epidermis might cause an infection if the surface of the skin breaks and the organism moves to the deeper lying tissues.

Hence, it could be that the patient was immunocompromised or the mirobiota moved to an unprotected sites within the body of the patient.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

its 42

i say its d?
