Why are invasive species a threat to biodiversity?

Invasive species are a threat to biodiversity because they have the ability to outcompete native species for resources such as food, water, and habitat. They often lack natural predators or diseases in their new environment, allowing them to reproduce rapidly and spread aggressively. This can lead to the displacement or extinction of native species, disrupting the natural balance of ecosystems. Invasive species can also alter the physical structure of habitats, degrade water quality, and reduce overall biodiversity. Additionally, they can introduce new diseases or parasites to native species, further impacting their survival. Overall, invasive species pose a significant threat to biodiversity by causing ecological imbalances and reducing the resilience of ecosystems.
