<em><u>Population is the level of organization that describes group of the same species that lives in the same area.</u></em>
Other levels of organization in an ecosystem are; organism, community, ecosystem, biome.
An organism is an individual living thing. Community is a group of different species that live together in one area. Therefore, a community is made up of several populations.
Ecosystem includes all of the organisms as well as the climate, soil, water, rocks and other non-living things in an area.
An imagined community is a concept developed by Benedict Anderson in his 1983 book Imagined Communities, to analyze nationalism. Anderson depicts a nation as a socially constructed community, imagined by the people who perceive themselves as part of that group.
