What does 'open system' describe in System Theory Terms?

A system with no energy exchange
A disorganized system
A system lacking clear goals
A system with cross-boundary exchange

The correct answer is: A system with cross-boundary exchange

An open system in System Theory Terms is one that allows for cross-boundary exchange, meaning it has interactions and connections with its environment. This makes options A, B, and C incorrect because they all describe a system that is closed off in some way. Option A indicates a system with no energy exchange and is therefore closed off from any input or output. Option B describes a disorganized system, which is also closed off as it lacks structure and clear connection with its environment. Option C suggests a system lacking clear goals, which means it is not actively engaging with its environment and is therefore closed. Only option D accurately describes an open system, as it acknowledges the importance of connections and exchanges between a system and its environment.
