In ecological terms, what does "invasive species" refer to?

The term "invasive species" specifically refers to an organism that is not native to a particular area and can cause harm to the environment, economy, or human health when introduced to a new habitat. These species often have abilities that allow them to outcompete local flora and fauna, such as rapid reproduction and growth, adaptability to various conditions, and lack of natural predators in their new environment.

Invasive species can significantly alter ecosystems, leading to biodiversity loss, as they may prey on or outcompete native organisms. This can disrupt local food webs and lead to negative ecological impacts, including the extinction of native species. Understanding the concept of invasive species is crucial in conservation efforts, as managing their spread can help protect local biodiversity and the overall health of ecosystems.
