Exotic species

Definition

Exotic species are organisms that are introduced into a non-native environment, often through human activity. They can disrupt local ecosystems and outcompete native species for resources.

5 Must Know Facts For Your Next Test

1. Exotic species can become invasive, causing significant ecological and economic harm.
2. Introduction pathways include accidental transport, intentional release, and natural dispersal.
3. Exotic species often lack natural predators in their new environments, allowing them to proliferate unchecked.
4. They can alter habitat structure, nutrient cycling, and food webs within the ecosystems they invade.
5. Management strategies include prevention, early detection, rapid response, and long-term control measures.
