Answer:
What are the three species?
(Correct me if I’m wrong )
Purple needle grass , wild oats , foxtail , ryegrass , and buffalo grass .
Since for it to be in scientific notation it has to be between 1 and 10. So what I did is move the decimal point over the left six times to get 5.098 x 10^6. So that is the answer, hope i helped you out.
