The correct arrangement from the largest to the smallest is:
1. Biosphere;
2. Biome;
3. Ecosystem;
4. Habitat;
The biosphere represents all of the places where the living organisms exist.
The biome represents a very large community of flora and fauna that has occurred naturally and is occupying a major habitat.
The ecosystem represents the biological community in which the organisms interact with each other, as well as their physical environment.
The habitat is representing the natural home or environment of a particular animal, plant, or of any other living organism.
