A compound is 2 different atoms…like H2O.

Therefore —–> All compounds are molecules, but not all molecules are compounds.

Mind Blown…Right! I know;)

Biomes

Ecosystems make up biomes. Do you have a favorite biome? Maybe a forest? Or an ocean?

Biospheres

Biomes make up our “life ball” ? …otherwise known as our “biosphere.” Get it bio=life and sphere=ball. Oh man, I’m still chuckling about that one.
