Which Species is Overexploited Rather Than Invasive

Question

Which species is overexploited rather than invasive?
A) zebra mussels in the Great Lakes
B) brown tree snakes of Guam
C) bison in the North American plains
D) marine toads in Florida
E) gypsy moth caterpillars in North America

Accepted Answer

Bison in the North American plains were overexploited by European settlers in the 19th century, leading to a drastic decline in their numbers. They have been protected since then, but their populations remain vulnerable and dependent on conservation efforts. The other species listed have become invasive in ecosystems outside their native range and have negative impacts on the ecosystem.
