Answer: Differences between microhabitat and microbiome-
A microhabitat is a smaller habitat within a larger one. It differs in characters from the surrounding, larger habitat. For example, a tidal pool at a beach.

A microbiome is the microbes, such as bacteria or fungi or viruses, that reside/live on an animal.
Fun fact: the human microbiome can weigh up to 5 lbs and have 200 times more genetic material than said human.
