Since invasive species did not co-evolve with the other species in the ecosystem where they were introduced species often unbalance the ecosystems into which they are introduced because they did not co-evolve with the natural species and lack natural controls, like predators.

Since invasive species did not co-evolve with native species in the ecosystem where they were introduced...often unbalance the ecosystem because they lack natural controls and predators.
