Invasive species can have significant negative impacts on native ecosystems. Some of the common impacts include outcompeting native species for resources such as food and habitat, disrupting the balance of the ecosystem, altering ecosystem dynamics, and reducing biodiversity. Invasive species can also introduce new diseases, predators, or parasites that native species are not equipped to deal with, leading to population declines or extinctions. Additionally, invasive species can change the physical structure of habitats, leading to further disruptions in the ecosystem. Overall, invasive species can have far-reaching and damaging effects on native ecosystems.
