How Introduced Species Affect Ecosystems
... • Many introduced species help or at least do not harm the ecosystem they come to. • However, some take over the habitat of the native species. These are called invasive species. • Invasive species often have high reproduction rates, are aggressive competitors, and lack natural predators. ...
