Final answer:
When resources are limited for a species, the population displays a logistic growth curve, which is S-shaped and levels off as the environment's carrying capacity is reached.
Step-by-step explanation:
Species with limited resources usually exhibit a logistic growth curve. When conditions allow for unlimited resources, population growth is exemplified by an exponential growth curve, which is represented by a J-shaped curve reflecting rapid and continuous population increase. In contrast, logistic growth occurs when population expansion slows down as resources become scarce and the population size eventually stabilizes once the carrying capacity of the environment is reached. A graph plotting logistic growth will yield an S-shaped curve.
