Which statement best describes an open system?

• A. It does not use feedback
• B. It is isolated from the environment
• C. It continually interacts with the environment
• D. It avoids change

Answer: (C)

Open systems continually exchange energy, matter, and information with their surroundings, using feedback to stay adaptive and functional. This constant interaction with the environment is what keeps the system responsive to new inputs and able to adjust its behavior as conditions change. In a foodservice context, a restaurant modifies inventory, staffing, and menus based on customer demand, supplier availability, and regulatory changes, illustrating this ongoing environmental interaction. That open systems describe is the one that best fits the idea of always interacting with the environment. The other statements don’t fit because not using feedback misses the mechanism that enables adaptation, being isolated from the environment describes a closed or isolated system, and avoiding change suggests a static, unresponsive setup.
