Answer:
D.They are introduced to an environment where they did not evolve but quickly adapt to it
Explanation:
Native Plants are the plants that are indeginous to a specific region for a long time. Hence, they create their own diversities and ecosystem. As they are prone to the pros(Eg :Soil Fertility) and cons( Eg: Less Sunlight) of their environment, they are well adapted to it and do not need additional requirements for their survival. Being plants, they form the basis of the food chain. However, they aren't introduced suddenly to the region, instead its a time taking process to adapt and evolve to their present location.
