Which includes living and nonliving organisms?

That would be ecosystem.

You have five levels of organization, which would be the biOSphere, ecosystem, community, population, and organism.

BiOSphere- All areas of the earth where life exist. The biOSphere made of large regions called biomes.

Ecosystem- All the living and nonliving things in an area.

Community- All the living things in an ecosystem.

Population- All the members of one species that live in an ecosystem.

Organism- A single living thing that is adapted to live in its habitat.

Hoped that help, excuse my errors.
