Invasive species are non-native organisms that, when introduced to a new environment, can disrupt local ecosystems. They often possess traits that allow them to grow rapidly, reproduce prolifically, and thrive in conditions that native species may not tolerate. This aggressive behavior enables invasive species to outcompete native species for resources such as food, space, and light.

Native species, by contrast, are those that have evolved in a particular region and are well adapted to the local conditions. Resilient species are those capable of recovering from disturbances but do not inherently pose a threat to native species. Endemic species are those found only in a specific geographic area; while they can be vulnerable, they do not compete with native species outside their range.

In summary, invasive species can significantly alter habitat dynamics and biodiversity by outcompeting and displacing native species, resulting in ecological imbalances.
