Invasive species can have a significant negative impact on native habitats by outcompeting native species for resources like food, water, and nesting sites. They can also disrupt ecosystems and alter the natural balance, leading to biodiversity loss. Additionally, some invasive species can introduce new diseases or parasites that native species are not equipped to handle. Overall, the presence of invasive species can result in the decline or even extinction of native species, and can have far-reaching ecological consequences.
