My thought process is that, after enough time, an invasive species of some plant or animal would find its way into its new ecosystem, and properly become a part of the ecological cycle? Does this ever happen? Maybe it just needs far more time to do so?
In: Biology
Something that might not have been mentioned is how invasive species destroy native organisms. Evolving in conjunction with the thing that will harm the organism gives it defensive traits and allows the species to carry on. Organisms usually produce significantly more offspring than will survive. Think about how five thousand fish eggs will only produce a handful of mature and reproductive organisms. So, when a species enters a new ecosystem devoid of predators, they are going to thrive and take over resources in the new ecosystem. Imagine how it works if the five thousand fish eggs hatch because they weren’t eaten by something else before hatching. From that point on, it’s a devastating domino effect. Of course, as has been mentioned, plants and animals can be introduced without being harmful.
