Final answer:
Invasive, native, and introduced species play distinct roles in ecosystems, impacting biodiversity and ecological balance.
Explanation:
Invasive species are exotic organisms introduced to a new area, where they threaten the ecosystem balance by outcompeting native species. They can rapidly spread and reduce biodiversity. Examples include pampas grass in the United States, which is actually native to South America.
Native species are plants or animals that naturally occur in a particular region. They play a key role in the local ecosystem and have adapted to the specific conditions of their habitat. In contrast to invasive species, native species are essential for maintaining ecological balance.
Introduced species are organisms intentionally or accidentally brought to a new area by human actions. While some introduced species may not cause harm, others can become invasive and disrupt the environment. Monitoring and managing introduced species are crucial to preserving native biodiversity.
