A limiting factor is a factor that limits the growth of a population’s size.

A limiting factor is a factor that limits the growth of a population’s size. It denotes the scarcity of essentials necessary for survival and growth. It could be non-availability of biotic factors like resources, food, mates, or abiotic factors like environmental imbalance, extreme weather conditions that stop or limit the growth of organisms in an ecosystem. Limiting factors are generally expressed as a lack of a particular resource that is essential for survival. It ultimately determines a habitat’s carrying capacity, which is the maximum size of the population it can support.

Ans. Limiting factors are usually the resources or environmental features that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem. This is known as limiting factors in ecology. This means that growth is controlled not by the total amount of resources available, but by the scarcest resource. A factor is limiting when a change in the factor produces increased growth, abundance, or distribution of an organism when other factors necessary to the organism’s life do not. Limiting factors are either biotic like food, mates, resources, etc. or abiotic like extreme weather conditions.
