Kudzu, a plant native to eastern Asia was introduced into America in 1876. In 1935, kudzu was planted along southern roadways to
control soil erosion. Adding a foot of vine a day in the spring and summer,
kudzu quickly grew out of control. Why can introducing a new species to an existing ecosystem often be a disaster?
А
The new species can harm native organisms and damage the ecosystem
B. The new species can create excess nutrients in the soil that can damage native species
C
The new species can eventually become extinct
D. The new species can rapidly evolve into a dangerous subspecies that cannot be destroyed.
