Kudzu, an Asian vine introduced to the United States in the 1930s as a means to control erosion, is referred to as "the plant that ate the South" because it grows so fast and overtakes most plant species in its path
A recent and unusual way that some people are using to control kudzu growth is to allow goats to graze their land and eat the kudzu, roots and all. This is considered by some to be the most environment-friendly way to eliminate this invasive vine. How can we best describe the goats in this situation? A) a threatened species
B) an invasive species
C) a biological control agent
D) an integrated pest management agent
