Detailed explanation-1: -The common limiting factors in an ecosystem are food, water, habitat, and mate. The availability of these factors will affect the carrying capacity of an environment. As the population increases, food demand increases as well. Since food is a limited resource, organisms will begin competing for it.

Detailed explanation-2: -A limiting factor is anything that constrains a population’s size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.

Detailed explanation-3: -Some examples of limits to population growth include energy available and absolute area. Other examples include disease, competition, human disturbances, access to water, etc. Population growth of any organism (humans, plants, animals, fungi, and so forth) is limited by the amount of energy available.

Detailed explanation-4: -Immigration is the permanent inward movement of some individuals coming from outside into an existing population. This increases population density and would not limits growth.

Detailed explanation-5: -True or false: Food is the only limiting factor that keeps populations from growing too large. False. It could also be water or shelter.
