The relationship between invasive species and native biodiversity is generally negative, as invasive species often outcompete native species for resources like food and habitat. They can disrupt local ecosystems, leading to declines or extinctions of native populations. Invasive species may introduce diseases or alter the natural balance, further threatening biodiversity. Managing invasive species is crucial for conservation efforts, as maintaining healthy ecosystems supports overall ecological stability and the long-term resilience of native species against environmental changes.
