Communities
A community in ecology refers to all of the populations in a specific area at a certain time. Communities have many types of interactions among species. Some of these interactions among species can lead to situation where individuals have a life or death struggle. Ecologists believe that a community with a high level of diversity is more complex and stable than a community that has a low diversity.
