Final answer:
The iguana population initially grew exponentially, but as resources dwindled, it shifted to logistic growth, stabilizing at the environment's carrying capacity.
Step-by-step explanation:
As the population grew in size and resources became limited, the population grew logistically. Initially, the iguana population may have increased exponentially, with rapid growth when resources were abundant. However, as the resources became scarce, the growth rate of the population slowed down and eventually became stable upon reaching a number that the environment could sustain, indicative of the carrying capacity of the iguanas' habitat.
