Detailed explanation-3: -An organism that harms the ecology or the economy in a new habitat where it is not native is referred to as an invasive species.

Detailed explanation-4: -Plants that do not occur naturally in a region but proliferate in the area they have been introduced into, and cause several negative impacts (such as affecting native biodiversity, causing economic losses and harming human health) in these new habitats, are called invasive plants.

Detailed explanation-5: -Pest species. Nuisance species. Weeds (or weedy, usually in reference to plants) Harmful non-native species.
