Explanation:
Detailed explanation-1: -Invasive alien species are among the main causes of biodiversity loss and species extinctions, and the proliferation of invasive species is often exacerbated by climate change.
Detailed explanation-2: -As species go extinct, they are taken out of the food chain. Animals that ate the newly-extinct species have to find new food sources or starve. This can damage the populations of other plants or animals. Furthermore, if a predator goes extinct, its prey’s population can proliferate, unbalancing local ecosystems.
