The ecological distinction between invasive and non-invasive species lies in their impact on native ecosystems. Invasive species are non-native organisms that, when introduced, can spread rapidly and disrupt local biodiversity. They may outcompete native species for resources, alter habitats, and lead to declines or extinctions. In contrast, non-invasive species do not significantly impact their new ecosystems and often coexist harmoniously with native species. The recognition of these differences is crucial for conservation strategies, as managing invasive species is essential for the preservation of ecosystem stability and biodiversity.
