12. Ecological Organization - Population
Population = organisms of the same species living together in a given location

Ecosystem = all of the different communities in a given location interacting with each other

15. Ecological Organization - Biome
Biome = a large region characterized by a specific type of climate and certain types of plants and animals

16. Ecological Organization - Biosphere
Biosphere = every living and non-living thing on the planet (portion of the Earth in which life exists)
