Detailed explanation-1: -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-2: -Limiting factors are environmental factors that keep a population’s numbers from growing out of control. Some examples of limiting factors are food, water, living space, and disease. The maximum number of any one organism an environment can support is the carrying capacity for that organism.
Detailed explanation-3: -These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.
Detailed explanation-4: -When demographers attempt to forecast changes in the size of a population, they typically focus on four main factors: fertility rates, mortality rates (life expectancy), the initial age profile of the population (whether it is relatively old or relatively young to begin with) and migration.
