A limiting factor limits the growth or development of an organism, population, or process.

Limiting Factors In Biology and Ecology

In biology, a limiting factor is a resource or environmental condition that limits the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem.^[1]^[2]^[3] The concept of limiting factors is based on Liebig's Law of the Minimum, which states that growth is controlled not by the total amount of resources available, but by the scarcest resource. In other words, a factor is limiting if a change in the factor produces increased growth, abundance or distribution of an organism, when other factors necessary to the organisms life do not. Limiting factors may be physical or biological.

Limiting factors are not all limited to the condition of the species. Some factors may be increased or reduced based on circumstances. An example of a limiting factor is sunlight in the rain forest, where growth is limited to all plants in the under story unless more light becomes available. This decreases a number of potential factors that could influence a biological process, but only one is in effect at any one place and time. This recognition that there is always a single limiting factor is vital in ecology; and the concept has parallels in numerous other processes. The limiting factor also causes competition between organisms in which of the same species population. For example, space is a limiting factor. Many predators and prey need a certain amount of space between another in order to receive enough food, water, and other biological needs. If there is too much population of a species, they start competing for those such needs. This makes some of the population to fade away either by starving or leaving the area due to lack of food in the space the organisms fought over.

Some other limiting factors in biology are weather conditions, and temperature. See Liebig's Law.

In business and technology

The AllBusiness.com Business Glossary defines a limiting (constraining) factor as an "item that restricts or limits production or sale of a given product." The examples provided include: "limited machine hours and labor-hours and shortage of materials and skilled labor. Other limiting factors may be cubic feet of display or warehouse space, or working capital."^[4] The term is also frequently used in technology literature.^[5]^[6]

BACKGROUND: Rice contains the lowest grain Fe content among cereals. One biological limiting factor is the tolerance of rice to Fe toxicity. Reverse and forward genetic screenings were used to identify tolerance to Fe toxicity in 4,500 M4 lines irradiated by fast neutrons (FN).FINDINGS: Fe-tolerant

The development of concrete corrosion in new sewer pipes undergoes an initiation process before reaching an active corrosion stage. This initiation period is assumed to last several months to years but the key factors affecting the process, and its duration, are not well understood. This study is th

日本の国土面積の65%を占める中山間地域では,急峻な地形を巧みに利用した棚田が数多く存在しており,その景観の美しさから,観光地としても発展を遂げている地域もある。本研究では地形という制約が土地利用変化に及ぼす影響を検討した。1987年から2006年の十日町市の土地利用変化を見ると,水田がもっとも大きく面積が変化した。そこで,土地利用の変化の中でも特に水田転用に焦点を当ててみると,水田転用後の土地利 …

… Yet, in the course of the 1930s, they grew in deliberate willingness and perception to engage in a wider scope of social dynamics without limiting themselves to the area of power politics. … In this paper, the manner in which these students and teachers gave meaning to their daily lives inside and outside of school is identified and analyzed as the factor that critically contributed to the emergence of political consciousness among them. …
