C. fill empty niches within the introduced range.
D. None of the above Correct Answers B. have fewer predators
and pathogens in the introduced range.
,Active intervention is likely needed to restore areas of high
productivity and low stress because:
A. such conditions could favor the rapid growth of invasive
species.
B. there may be few seeds of native plant species present in such
areas.
C. these conditions foster a higher rate of erosion.
D. None of the above Correct Answers A. such conditions
could favor the rapid growth of invasive species
