Detailed explanation-3: -Biologists recognize 12 levels of organization in the living world. From the simplest to the most complex, these levels include atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and finally biospheres.

Detailed explanation-4: -From largest to smallest: biosphere, biome, ecosystem, community, population, and organism.

Detailed explanation-5: -The biosphere is sometimes thought of as one large ecosystem-a complex community of living and nonliving things functioning as a single unit. More often, however, the biosphere is described as having many ecosystems.
