Answer:This species of grass would be classified as an INVASIVE species.
Explanation:
An invasive species is an animal or a plant that comes from another part of the world into another place where it is not originally from and it starts to grow or live there, invading the original or native species.
They are usually carried into other regions through ship ballast water and in most cases by people (through food from other countries or attached in clothes that were worn in another region)
The negative effect of these species is that can destroy the native species, cause extinction of the native species,harm the natural resources and affect how human use of these natural resources.
They are very competitive and can compete with the native species for limited resources hence they end up changing and disrupting the natural habitat of the native species. This affect the overall ecosystem and biodiversity.
