Keystone Species

Why do some species only live in one part of the world, even though there are other environments which could be suitable? One outstanding case of a species surviving in one specific area is the kangaroos. This, can be called “The kangaroo question.” Kangaroos can only be found in Australia, even though there are several other habitable areas for them. Then why do some species only stay in an undivided field of nation? There could be many reasons for this phenomenon. The most obvious response would be because of certain weather and climate factors that don't provide optimal environments for them. But suppose they do sustain a perfect environment, that still doesn't mean the species will be found in that location. Some other factor could only be the geographical area they are from. There could be many obstacles such as oceans or mountains and other inhospitable places confining them to certain areas. Straight off, lets say that a species found a compatible environment and it was easy to stick to. At that place could be predators, insufficient resources, etc. that could conduce to the ruination of the coinages. …show more content…
Present an instance of one keystone species and describe its environment. Speculate on changes to the environment which could occur if that particular species disappeared. Give specific reasons for each variety. The keystone species, is a phenomenon in which a certain species keep the proportion of an ecosystem in check. Sea otters, are a great example of a keystone species. Because, they keep sea urchins from consuming and destroying large kelp fields. If the otters were to disappear urchins would thrive and valuable kelp fields would be
