Invasive species are organisms that cause harm to the environment in which they are introduced. Some synonyms for this term include "alien species," "non-native species," or "exotic species." These terms all describe organisms that are introduced to a new environment, either intentionally or unintentionally, and have a negative impact on the native species. Other synonyms for invasive species include "injurious species," "noxious species," or "weedy species." These terms highlight the detrimental effects of these organisms and emphasize the need to control their spread and mitigate their impact on the environment. Choosing the right term to describe these species is important in raising public awareness about the issue.
