Editing Ecological niche (section)

==Parameters==
The different dimensions, or ''plot axes'', of a niche represent different [[Biotic component|biotic]] and [[Abiotic component|abiotic]] variables. These factors may include descriptions of the organism's [[Biological life cycle|life history]], [[Habitat (ecology)|habitat]], trophic position (place in the [[food chain]]), and geographic range. According to the [[competitive exclusion principle]], no two species can occupy the same niche in the same environment for a long time. The parameters of a realized niche are described by the [[realized niche width]] of that species.<ref name="Hardin" /> Some plants and animals, called [[Generalist and specialist species|specialists]], need specific habitats and surroundings to survive, such as the [[spotted owl]], which lives specifically in old growth forests. Other plants and animals, called generalists, are not as particular and can survive in a range of conditions, for example the [[dandelion]].<ref>{{Cite book |title=An Introduction to Human-Environment Geography |last1=Moseley |first1=William |last2=Perramond |first2=Eric|last3=Hapke|first3=Holly |last4=Laris |first4=Paul |publisher=Wiley Blackwell |year=2014 |isbn=978-1-4051-8932-3 |location=West Sussex, UK |page=81}}</ref>
