Detailed explanation-1: -An invasive species is an organism that is not indigenous, or native, to a particular area. Invasive species can cause great economic and environmental harm to the new area.

Detailed explanation-2: -Exotic predators are arguably the most disruptive group of introduced species [2, 6], as they often exert impacts on native species far greater than those attributed to their native counterparts [7–9] and they are implicated in the extinction of hundreds of native species [1, 2].

Detailed explanation-3: -The species of plants or animals which are non-native to the introduced environment are known as exotic species. Exotic species will compete for food, resources, and predation in an ecosystem. They are also known as invasive species as they threaten the native species.
