You're very close! It's not "bio mes," but biomes that make up the biosphere. Here's the breakdown:

* Biomes: Large-scale ecosystems characterized by specific climate conditions and dominant plant and animal life. Examples include forests, grasslands, deserts, and oceans.

* Biosphere: The sum of all living things and their environments on Earth. It encompasses all biomes.

So, biomes are the individual pieces that make up the larger whole, the biosphere.
