Organisms are groups of molecules (and possibly atoms) joined together to form distinct section of an interface.
Organisms can consist of similar and/or disparate molecule types. For example, a masthead organism might consist of a logo, navigation, and search form, while a “product grid” organism might consist of the same product info molecule repeated over and over.
