Non-native species: Non-native species are organisms that have been introduced to an area outside their natural range. They may or may not become invasive.
Biodiversity: Biodiversity refers to the variety of life forms in a particular habitat or on Earth as a whole. Invasive species can negatively impact biodiversity by reducing the number of native species.
Ecological disruption: Ecological disruption occurs when there is a disturbance or alteration in an ecosystem's structure or function. Invasive species often cause ecological disruptions by changing resource availability and interactions among organisms.
