What would be the signs that carrying capacity was being exceeded?

Signs that carrying capacity is being exceeded include a decline in resource availability, such as food and water shortages, leading to competition among species. There may also be observable increases in stress-related behaviors, such as aggression or disease prevalence in wildlife populations. Additionally, environmental degradation, such as soil erosion and loss of vegetation, can indicate that the ecosystem is unable to sustain its current population levels. Lastly, increased mortality rates and decreased reproductive success can signal that the habitat is overburdened.
