Ah ok! The difference would be the factors, they’re included in each level of organization!
Explanation:
First, let's review biotic and abiotic factors.
Biotic factors are living organisms, an example would be a deer.
Abiotic factors are non-living objects, an example would be the air.
Population - All the members of one species that live in a defined area.
Community - All the different species that live together in an area.
Ecosystem - All the living and non-living components of an area.
I hope this helped a bit ^^
