Invasive species can disrupt ecosystem dynamics by outcompeting native species for resources, altering habitat structures, and introducing diseases. Their presence can lead to declines in native biodiversity, affecting food webs and ecological relationships. For example, invasive predators can drastically reduce populations of native prey species, while invasive plants can shift landscape composition. These changes can compromise ecosystem services, such as water purification and pollination. Addressing the impact of invasive species through management and prevention strategies is essential to maintain ecological integrity.
