Earth & Environmental Science Final Review

When taken to a new habitat, non-native plants often threaten native plants of the new habitat.  Why do they do this?

• Non-native plants are able to mutate rapidly
• Non-native  plants cause native animals to relocate
• Non-native plants are able to be used for medicine
• Non-native plants compete with native plants for resources
