Quizplus · Accepted Answer

A habitat island doesn't necessarily have to be an actual island surrounded by water; it can be any area that is distinctly different from its surroundings and can support unique ecosystems. A lake surrounded by trees acts as a habitat island for aquatic species, a patch of moss on a tree trunk serves as a microhabitat island for small organisms, and metaphorically, a person in line could be considered a moving habitat island for microorganisms.
