Detailed explanation-1: -Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment.

Detailed explanation-2: -The population growth rate will be limited by various factors in the environment. For example, birth rates may decrease due to limited food or death rate increase due to rapid spread of disease as individuals encounter one another more often.

Detailed explanation-3: -Limiting factors are biotic (living) and abiotic (non-living) things in an ecosystem that prevent a population from growing any larger.

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.
