Limited resources among members of a population lead to heightened levels of competition as individuals strive to secure what is necessary for survival, such as food, water, shelter, and mates. When resources are scarce, individuals compete more aggressively, which can influence behaviors, social structures, and even evolutionary outcomes within the population.

This competition may manifest in various forms, such as aggressive behaviors, territorial disputes, or social hierarchies, all serving as mechanisms to ensure that individuals have access to the needed resources. In ecological terms, this increased competition can lead to reduced population sizes over time or drive changes in reproductive strategies, as individuals must optimize their resource acquisition to thrive in a challenging environment.

In contrast, the other options either depict scenarios that are not directly related to resource limitations or imply positive interactions that typically do not flourish under conditions of scarcity. For instance, symbiotic relationships can be impacted by resource availability but do not inherently emerge as a consequence of limited resources. Similarly, increased fertility rates would not usually occur in resource-limited contexts, as parents may be less able to support larger offspring quantities. Lastly, a reduced need for predation implies a stable prey population that might be at odds with the existence of limited resources, which typically leads to an increased reliance
