Fundamental Vs Realized Niche

In a fundamental niche an organism can take advantage of all the biotic and abiotic factors in an ecosystem without competition from other species or pressure from predators. Realized niche is the set of conditions actually used by given animal pop species after interactions with other species predation and especially competition have been taken into account.

Moreover a further difference between fundamental and realized niche is that the fundamental niche describes the various ecological roles that a species can attain.

Fundamental vs realized niche. In contrast the realized nicheis the niche the species actually occupies. The entire possible niche that a species may occupy a tree realized niche. The actual niche within the fundamental niche that a species does occupy specific area of a tree multiple species.

The fundamental niche refers to a range of conditions roles and resources under which a species survives grows and reproduces. Therefore this is the key difference between the fundamental and realized niche. The main difference between fundamental niche and realized niche is that the fundamental niche is any type of environmental condition in which a particular species can live whereas the realized niche is where the species actually live.

If balanus was removed from the lower strata chthamalus was able to occupy its fundamental niche both upper and lower strata which is much larger than its realized niche of upper strata. May have same fundamental niche but as a result of adaptations and competition each finds its own realized niche. Niche can be either fundamental niche or a realized niche.

On the other hand realized niche is the actual area that a species is found. This can be thought of as the textbook version of a niche. Fundamental vs realized niche.

While a fundamental niche elaborates on the various roles of the species the realized niche elaborates on what the species actually do. Fundamental niche is the natural area where a species can live and reproduce. A fundamental nicheis the niche the species would ideally occupy or could theoretically occupy.

Fundamental niche is the entire set of conditions under which an animal population species can survive and reproduce itself. It is the niche the species occupies in absence of other competitors. Other names for these niches are precompetitive and postcompetitive respectively.

In a fundamental niche there is no competition for resources or predators while in a realized niche there is a competition for both resources and predators. Fundamental niches represent all the environmental conditions where a species is able to live and the realized niche is where the species actually lives.
