Invasive species are organisms (plants, animals, or microorganisms) that are introduced into an ecosystem where they are not native. These species can spread and reproduce quickly, and they often outcompete native species for resources such as food, water, and shelter. Because invasive species don’t have natural predators or controls in their new environment, they can rapidly multiply and disrupt the balance of the ecosystem.

The impact of invasive species on ecosystems can be significant. They can reduce the diversity of native species and even cause the extinction of some species. Invasive plants may grow aggressively and outcompete native plants, leading to the loss of habitat for native wildlife. Invasive animals can prey on native species, disrupt food chains, and even alter the physical structure of ecosystems.

Preventing the introduction and spread of invasive species is crucial to protect native ecosystems. This can be achieved through actions like monitoring and controlling the transport of non-native species, implementing regulations on international trade, and raising awareness about the risks and impacts of invasive species.
