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: -Types of Limiting Factors A large, dense population is more strongly affected than a small or less dense population. For example, a dense population would have higher demands for food and water compared to a small population. In this case, food and water supply is the limiting factor and it depends on density.
Detailed explanation-3: -Limiting factors include a low food supply and lack of space. Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.
