For the growth curve to keep increasing, it is essential that resources in the environment are unlimited. This condition supports the ability of a population to grow at its maximum potential, as there are no constraints on food, space, or other necessary resources that organisms need to survive and reproduce. When resources are plentiful, organisms can utilize them without competition, leading to higher reproductive rates and lower mortality, which directly contributes to exponential growth.

In contrast, limited resources would cap the growth of a population, as individuals would compete for those scarce supplies. Factors such as increased competition or the presence of predators could further hinder growth by reducing the survival rates of organisms or limiting their reproductive success. Thus, for a population to experience continuous growth, an environment with abundant and accessible resources is crucial.
