However, it is incredibly difficult -at this time- for us to determine why some of the much older species became extinct, so it would not be correct to assume that they followed the patterns that we see today. As the predators population decreases, the prey's population will be able to increase resulting in a pattern where neither species ever dies out completely. If a population of prey begins to deplete, the predator population will deplete at a much faster rate this is due to the exchange of energy within the system being fairly inefficient. In modern species, a predator will never deplete its food source completely. Species (as far as we know) can only become extinct due to an environmental change causing their likelyhood of survival to decrease. I am writing this from my phone, so I apologise for any mistakes that I have made, and perhaps a lack of detail or completion to my thoughts.īelieve it or not, there is absolutely no known example of a species causing its own extinction. We make our world significant by the courage of our questions and by the depth of our answers. ![]()
