What is the organizational level of a biome from the broadest category to the most specific catergory?

The organizational level of a biome, from the broadest to the most specific category, starts with the biOSphere, which encompasses all living organisms on Earth. Within the biOSphere, biomes are defined as large ecological areas characterized by specific climate conditions, flora, and fauna. Each biome can be further divided into smaller ecosystems, which consist of communities of organisms interacting with their environment. Finally, within these ecosystems, specific habitats and individual species represent the most specific categories.
