Competition.
But more to the point it depends on the species.
The Lokta-Volterra equations can be used to produce isoclines that show the expected result but in simpler terms it depends on how well each reproduces and who was there first. Sometimes either species will "win" and force the other out and other times they may find equilibrium where both coexist.
On longer timescales the first species that gets the opportunity will generally evolve into a different niche will often take it and move out of the overlap.

What way leads to competition between two species?
An overlap in their niches
Can two species occupy different niches and the same habitat?
Yes. There are different niches in the same habitat.
How do cat tails and grass share the same niches?
no
What are lap sutures?
overlapping edges
What is is the difference between interspecific competition and intraspecific competition?
Interspecific : Interspecific competition, in ecology, is a form of competition in which individuals of different species vie for the same resource in an ecosystem (e.g. food or living space). The other form of competition is intraspecific competition, which involves organisms of the same species.Intraspecific : Intraspecific competition is a particular form of competition in which members of the same species vie for the same resource in an ecosystem (e.g. food, light, nutrients, space). This can be contrasted with Interspecific competition, in which different species compete.Source(s):Google Definitions
What happens when two organisms attempt to occupy the same niches?
COMPETITION competition
What leads two species to competition?
an overlap in their niches
Is competition between two species reduced when the species have different niches?
True
What has most likely caused the realized niches of these two wildflower populations to be smaller than their fundamental niches?
Competition has restricted the ranges of both species.
Organisms with overlapping niches probably have which type of relationship?
Likely competition. An organism's niche is the specific environment in which they live and procreate the best (which includes climate, food sources, places to live and escape from predators, etc.). An overlap of two different species niches means that the resources these organisms depend on are now in shorter supply. This means they must compete with the other organisms for survival
How does the idea of niches explain how similar species can coexist with a minimum of competition?
it means that they connect in 1 way or an other! :D
What three items do evolutionists disagree about?
One is that evolution occurs gradually and consistently.The other is that evolution occurs as a result of competition for 'niches'
What is the niche of the tiger?
To be specific niches exist because competition of biotic and abiotic factors affect the distribution of particular species to a specific niche because it is preferable to live in different niches, it results in less inter-species competition and the less competition there is, means more food, therefore more chance of survival. Niches are what help make eco-systems function so systematicly and perfectly. [that is without human interruption] Every animal has a unique niche. A tigers niche would be specifically where it lives, what it eats and what it contributes to the eco-system it's located.
What leads competition between two species?
an overlap in their niches
How can competition between species influence the niches of both pecies?
Species that occupy different niches are not likely to compete. This is because each of the species will probably eat different things and seek different types of shelters. They will not need each other's resources.
Why do adaptive radiations often occur after mass extinctions?
After a mass extinction event many niches are left empty. New species eventually evolve and fill the niches where competition would otherwise have prevented such evolution.
What accounts for the dinosaurs' rise to dominance at the start of the Jurassic Period?
At the beginning of the Triassic period, a mass extinction wiped out most large land animals. The remaining animals quickly evolved to fill the empty niches, and one line led to the earliest dinosaurs. Another, less severe, mass extinction at the end of the Triassic eliminated the animals that were significant competition to the dinosaurs. With these animals out of the way, dinosaurs quickly diversified to fill the empty niches.
