The term "organic" can refer to various concepts, but if you're asking about an organic entity that functions continuously for 24 hours, the human body is a great example. Various biological processes and functions in the body, such as the circulatory system, respiration, and metabolic processes, operate continuously around the clock to maintain life.
If you meant something else by "organic" or were referring to a specific context (like an organization or system), please specify so I can provide a more accurate response!
