The Abert’s squirrel is found on the south rim of the grand canyon and surrounding states.The Kaibab squirrel can only be found at the north rim of the canyon.<span>Scientists believe they were separated by plateau erosion that separated the forests of the Grand Canyon, isolating the Kaibab population of squirrels.</span>
<span>Abert's squirrels (Sciurus aberti) are a North American species, found across a range of locations. Kaibab squirrels (Sciurus aberti kaibabensis) are a subspecies of Abert's squirrels, found only in one area in the United States. As these two types of squirrels have been isolated from one another for 10,000 years, they've evolved some distinct and separate characteristics.
Organisms that can only grow in a media having specific nutrients included in it are called a fastidious organism, this implies that these organisms have specific nutrient requirements for their growth.
MM 1 represents the minimal media which has basic nutrients present in it, however as the fastidious organisms require some particular or complex nutrients for their growth they can not grow on the minimal media.
Therefore, since the organisms that are given in the question is able to grow on the minimal media MM1, this implies that it is not a fastidious organism.
