A population of ten mating pairs of butterflies colonize a new area with no predators and a number of flower species large enough to support a butterfly population of 2000 individuals. Each pair can have 20 offspring per year. For the first 2 years in the new area, the growth curve for this butterfly population will show: exponential growth because the colonizing population size will remain below the carrying capacity for the first two years. logistic growth because they will reach maximum population size immediately after colonization. exponential growth because only a few individuals will have offspring. logistic growth because the colonizing population will reach carrying capacity within the first two years.
