Researchers working with rob dunn set out to collect and identify microbes found in belly buttons. when the researchers began identifying these microbes, they found that the microbes represented a wide range of metabolic activities. for example, one microbe might be able to break down sugars found in the belly button for energy, but only in the absence of oxygen. what terms would you use to describe this microbe:

They are Obligate anaerobes.

Explanation:

Obligate anaerobes are microorganisms that survive and strive well in the absence of oxygen. Presence of oxygen is lethal to obligate anaerobes. Obligate anaerobes lack superoxide dismutase and catalase or peroxidase enzymes which make oxygen concentration to be lethal to them. Obligate anaerobes are poisoned and inhibited by oxygen. Examples include clostridium and bacteriods. These bacteria obtain energy through anaerobic respiration and fermentation process where they obtain little amount of ATP. They are much different from Obligate aerobes, as obligate aerobes require oxygen to to survive.
