Final answer:
Due to unlimited resources, the population of iguanas grew exponentially, characterized by rapid increases that eventually transitioned to logistic growth as they reached the carrying capacity of their environment.
Step-by-step explanation:
Complete the sentence about the changes that occurred in the growth of the iguana population over time: Due to the unlimited resources, the population grew exponentially.
When unlimited resources are available, populations tend to exhibit exponential growth, which can be described as a rapid and accelerating increase in population size. This pattern of growth is often depicted by a J-shaped curve, indicating the accelerating rate at which the number of individuals in the population increases. However, once resources become limited, exponential growth typically transitions to logistic growth, where the growth rate slows down, and the population size stabilizes at the carrying capacity of the environment. The carrying capacity is the maximum number of individuals that a given environment can sustain indefinitely without being degraded.
Based on the provided information, several scenarios demonstrate a transition from exponential growth to logistic growth, as the iguana population stabilizes at a certain number, which seems to be the carrying capacity of the ecosystem they inhabit.
