The habitat is where an organism lives and has many different organisms within it. The niche is the purpose that organism fulfills in that habitat. No two species can occupy the same niche in the same habitat due to competition for that role.
The Law of competitive exclusion, also known as Gause's Law, has been paraphrased into the maxim "complete competitors cannot coexist".
the competitive exclusion hypothesis
As the ocelot has a vast range that extends from extreme southern Texas all the way south into much of South America and much of the habitat they occupy is in remote areas, it is unknown how many ocelots remain. It is a fairly common animal in much of its range and listed as a species of least concern. The population in the United States is quite small so it is listed as an endangered species in that country.
Faunal succession
Nudibranch Behaviour (Behrens 2005) states that estimates put numbers at over 2000 species.
Superposition
Yes. The primary cause for population decline is the loss of habitat by agricultural and urban conversation. Also because of overharvesting for pet trade. ================================================== Actually, that depends on the specific species and the state. There are 8 species of Horned Lizard native to the US. Most are granted protection in most of the states; but, not all species, and not in all states. None are listed as federally endangered yet. They are considered "threatened". In some states, such as Texas or California, "threatened" is treated as the same as "endangered". Some states list them as "species of special concern", and have limitations on collection or require a hunting license. In most states, where they are protected as "threatened", a scientific collection or commercial permit is required to collect or possess them. In these states, it is a wildlife code violation to possess without permit. Penalties may range as high as $1000 fine per violation and/or 1 year in jail. The reasons for population decline are primarily loss of habitat, agricultural activities, pesticide use, invasive species such as fire ants, predation, and collection for pet trade.
The principle of competitive exclusion states that two species cannot occupy the same niche. If they do occupy the same niche, competition for food, space and limited resources will occur. Too much competition will occur until the best-adapted species cause the disappearance of the other.
The competitive exclusion principle states that no two species can coexist if they occupy the same niche and compete for the same resources.There are two possible outcomes of the competition:One species is less capable and becomes extinct.One species undergoes an evolutionary or behavioral shift towards a different ecological niche.

A single species, or two species that occupy different niches in the same range and use different resources. Darwin's finches are an example of this. Large strong beaks take the large seeds and small beaks take the lesser seeds as resources.
It's called Pauli (http://en.wikipedia.org/wiki/Wolfgang_Pauli) exclusion principle and it states that no two identical fermions may occupy the same quantum state simultaneously.
Pauli's principle states that no two electrons in the same atom can occupy the same quantum state, so that excludes the possibility of two electrons having the same quantum state in an atom

The competitive evolution principle is often called Gause's Law of Competitive Exclusion. This principle states that two different species competing for the same things cannot coexist.
yes, theses ancestors are called common decent
