Final answer:
Natural systems are those that occur naturally in the environment, while man-made systems are created by humans for specific purposes.
Step-by-step explanation:
Natural systems refer to systems that occur naturally in the environment and are not created by humans. Examples of natural systems include weather patterns, the water cycle, and ecosystems. Natural systems follow natural laws and processes.
Man-made systems, on the other hand, are created by humans to serve specific purposes. They are designed and controlled by humans. Examples of man-made systems include transportation systems (such as highways and railways), communication systems (such as the internet and telephone networks), and social systems (such as governments and economic systems).
