There are only so many available resources such as food, territory, predators (to help control the number so it does not get out of hand, and for sessile organisms a limited amount of rocks.
Factors that can limit the size of a population are known as limiting factors. These include biotic elements like predators, competition for resources, and disease, as well as abiotic elements such as drought, temperature extremes, and availability of water and nutrients. Both sets of factors interact to regulate population growth and maintain ecological balance. Ultimately, they can determine the carrying capacity of an environment for a particular species.
Unrestricted growth refers to a situation where a population or system can increase without any limitations or constraints. In this scenario, resources are abundant, and there are no factors that impede the growth of the population. This can lead to exponential or rapid growth until environmental factors eventually limit further expansion.
Predation can decrease a population by directly killing individuals. Competition for resources can limit population growth by reducing access to food, mates, or other necessities. Crowding and stress can also limit population growth by increasing competition, reducing reproductive success, and weakening immune systems, making individuals more vulnerable to disease.
If resources are limitless than a population's growth will be exponential. Growth will be logistic in cases where there are limited resources. As the population grows closer to the logistical limit, the overall growth will slow.

Hello! It's most likely that the population growth of bats living in a cave will be affected by a volcanic eruption, a flood and/or an earthquake. I hope this helps. ~Your Bio Buddy

Population growth is limited by the ability of the natural environment to sustain it. It can be limited by food shortages or a lack of shelter. Disease outbreaks can also limit population growth.
Shorter life expectancy, incurable disease, over population and not enough food can limit population growth

Population growth is determined by the difference between the birth rate and the death rate within a given population. When the birth rate exceeds the death rate, the population grows, and when the death rate exceeds the birth rate, the population declines. Migration can also impact population growth by adding or subtracting individuals from the population.
Birth Control is what is most likely to limit human population growth.

the number of hamburgers available from McDonalds greatly limits the population.
Antinatalist countries, such as China and India, have policies in place to limit population growth. These policies include restrictions on family size, incentives for sterilization, and education programs promoting smaller families.
