Flea beetles alone are unlikely to eliminate all of the leafy spurges in a region. Instead, the number of leafy spurge plants and the number of flea beetles in a particular community may stabilize. At this point, the leafy spurge and flea beetle populations:
(a) have exhibited exponential growth followed by a crash
(b) have experienced constant growth
(c) are still experiencing exponential growth
(d) are experiencing environmental resistance
