Define the term invasive species and give two examples from your textbook
What will be an ideal response?
Invasive species originate from ecosystems usually far removed from the one into which they are introduced. They are capable of attaining unnatural dominance within ecological communities. Many are introduced by humans, in some cases intentionally. In many more cases, they are introduced unintentionally. In their new environment, invasive species have little or no restraint on their population growth. Examples include zebra mussels, sea lampreys, chestnut blight fungus, and Dutch elm disease.
