There are various levels of organization from which a biosphere is made up of and they are as follows:
Individual is a single organism living in an environment. Population is a group of individuals living together in a given geographical area. These individuals are so similar that they can interbreed and produce offspring. A community contains number of different species living together in a distinct area. Ecosystem is formed when all the living organisms and non living components of a place are collectively referred. Biome is formed when group of ecosystem having similar climate and similar communities come together. A biosphere is a union of different biomes to form the final organization level.
