What is a significant consequence of invasive species on ecosystems?

Invasive species are non-native organisms that, when introduced to a new environment, can disrupt local ecosystems. One of the most significant consequences of their presence is their tendency to negatively impact native species. Invasive species can outcompete native organisms for resources such as food, space, and light, often due to their accelerated growth rates, reproductive advantages, or lack of natural predators in the new environment. This competitive advantage can lead to a decline or even extinction of native species, thereby reducing biodiversity.

Moreover, invasive species can alter habitat structures and change the interactions among species within the ecosystem, leading to further negative consequences for native flora and fauna. They may also introduce diseases to which native species have no resistance. All these factors contribute to weakened ecosystem stability and resilience, highlighting the detrimental effects invasive species can have on the ecological balance.
