False. Check out marine phytoplankton — several different species occupying the same niche at the same time.
Ignoring that for the moment, your teacher wants some spew about Gause’s Competetive Exclusion Principle.http://en.wikipedia.org/wiki/Competitive…
The idea here is that one of them is going to be a better competitor than the other for resources such as food, and, over time the worse competitor will either adapt to a different niche, or become locally extinct.
