Explanation:
The biosphere is made up of both living and non living things, which interact continuously with one another. The components of biosphere are organized in levels, depending on the number of component in each level. The hierarchy of arrangement from the most inclusive to the least inclusive are as follows: biosphere, ecosystem, community, population, individual organism. The individual organism can be broken down into system, organ, tissues, cell and organelle.
