A limiting factor causes a population to decrease in size. A few limiting factors are food, shelter, water, space. These are not all limited to the condition of the species. Somefactors 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 plants photosynthesis.
A number of potential factors could influence a biological process, but importantly only one is limiting 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.
Some other limiting factors in biology are water availability, temperature, shelter, or predatation. See Liebig's Law.
Famous quotes containing the words limiting and/or factor:
“There could be no fairer destiny for any physical theory than that it should point the way to a more comprehensive theory in which it lives on as a limiting case.”
—Albert Einstein (1879–1955)
“In his very rejection of art Walt Whitman is an artist. He tried to produce a certain effect by certain means and he succeeded.... He stands apart, and the chief value of his work is in its prophecy, not in its performance. He has begun a prelude to larger themes. He is the herald to a new era. As a man he is the precursor of a fresh type. He is a factor in the heroic and spiritual evolution of the human being. If Poetry has passed him by, Philosophy will take note of him.”
—Oscar Wilde (1854–1900)
