Affiliate Marketing Secrets

For a science poster I have to arrange some terms from “biggest” to “smallest” based on how where the terms fit in a biosphere. My teacher assigned this project before we have actually started the unit, so we haven’t learned this yet and I don’t know if I have them in the right order. These are the words in the order I put them in:
Biosphere
Biome
Ecosystem
Community
Population
Habitat
Niche
Organism
Is this how you would have ordered them? I know for sure that the first and last terms are right, but I’m not sure about the rest.
