Communities Communities of plants, animals, and other organisms may be found in such places as a desert, a  salt marsh, or a forest. Within a  community , each population of organisms has a habitat and niche.  The habitat is the physical place where the organisms live, while the niche is the role that the  population plays in the life of the community. The niche is the population's function and position in  the ecosystem, and it reflects the population's relationship to other populations. A population's niche  is defined by how and when it reproduces, what time of the day and year it is most active, what  climatic factors it can withstand, what it eats, and so forth. The competition exclusion principle  suggests that two species cannot occupy the same niche in the same place at the same time.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
