When a non native species is imported into a new ecosystem the population sometimes runs wild. explain why this might be the case

    Well, there are a few explanations to this questions that could be right, but let's go to the obvious one.

    What can happen sometimes is that, when a new species is imported into a new ecosystem, it can cause some problems. For example, a plant is imported from Japan to Brazil and it is planted in the soil of a forest. This plant can either adapt to the environment or die because it's missing nutrients from Japanese soil. If this plant adapts, it can happen to in a way that this plant will take place of plants that usually were growing right there, taking their resources to grow up more and more, spreading fastly too. That is a process that can happen, it's a possibility, but, there's a very big chance of this happening in reality.

     We can either mention the example of an animal, it's easier to understand, if we put a new animal into a new environment, it can go wild because this animal can start eating other animals, and that can cause a serious problem for their population, since it's going to start growing faster and faster, and once this happens, it'll will reach a limit line, and that line is the line of competition for food.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
