Which type of system continuously interacts with its environment and adapts to changes?

An open system is characterized by continuous interaction with its environment, allowing for the exchange of information, energy, or resources. This adaptability enables open systems to respond to external changes effectively, making them dynamic and responsive to their surroundings. In psychology and other fields, understanding individuals or organizations as open systems can provide valuable insights into how they adapt, evolve, and maintain functionality amidst varying conditions.

In contrast, a closed system does not interact with its environment or has limited interaction, which restricts its ability to adapt to changes. An isolated system is even more extreme, as it does not exchange matter or energy with its environment at all. A static system, meanwhile, implies a lack of change or adaptation over time. Thus, by recognizing that an open system is equipped to continuously adapt through interaction, one can see why this is the correct answer in the context of systems theory.
