The impact of invasive species on local biodiversity can be profoundly negative. Invasive species often outcompete native species for resources such as food and habitat, leading to a decrease in native populations. This can also disrupt local ecosystems by altering nutrient cycles and energy flows. Additionally, invasive species may introduce new diseases that native species have no resistance to, further exacerbating their decline. The loss of native species can reduce overall biodiversity, affecting ecosystem resilience and stability.
