Explain why the fact that invasive species did not co-evolve with the native species unbalances an ecosystem.

Explanation:

An invasive species is the one which is introduced into a new habitat either accidentally or intentionally by humans are capable of negatively affecting the  ecosystem of the new habitat. They compete with the native species for food, shelter and other resources. This leads to the reduction in number, migration and extinction of the native species. This unbalances an ecosystem. Therefore, invasive species does not co-evolve with the native species.
