The principle of competitive exclusion states that a. two species cannot coexist in the same habitat. b. competition between two species always causes extinction or emigration of one species. c. two species that have exactly the same niche cannot coexist in a community. d. two species will stop reproducing until one species leaves the habitat.

Hello everyone. And in today's video we have the following problem that two species that have exactly the same niche cannot coexist in a community. This is referred to us and we're giving a few principles or hypothesis that could apply to this scenario before we jump into solving this problem. Let us visualize the scenario that we have here. We have two species as we see and these two species have the same niche, which means that they have the same needs and they are competing for the same resources. Since these species are competing for the same resources, one of them eventually is gonna be the better competitor and it's going to exclude the other one is going to drive it either to extinction or to move away from the niche. Now that we know this, let us just be let us recall each of the principles and hypotheses that were given so that we can solve the problem. So remember that keep in mind that we are looking for a principle that applies to competition for the same resources. So intermediate disturbance hypothesis or option D. Is a hypothesis that correlates to species diversity has nothing to do with competition. So we're going to cancel it out. Natural selection is a very popular principle and it has to do with the selection of trades due to natural pressure. And so we're going to cancel that as well as it really has nothing to do with competition for these same niche. The principle of inheritance. Just it has to do with the passing of traits from parents to offspring. So there's nothing to do with competition for the same trade for the same trades. And that leaves us with answer choice A which is the principle of competitive exclusion. So there were competitive exclusion says they are all on itself. It's about just competition. That is going to exclude one of the species or the species that is not as adapted for the niche. And so that is exactly what it is. Is competition for the same resources and it's going to apply perfectly to our answer choice so that it's going to be our final answer. So thank you very much for sticking around until the end of this video. I really hope this video helped you and I hope to see you on the next one.
