Explanation:

Natural Resource - Air:
- Air is a natural resource that is essential for the survival of all living organisms on Earth.
- It is composed of gases such as oxygen, nitrogen, and carbon dioxide, which are crucial for various biological processes.
- Air is freely available in the environment and is not created by humans, making it a natural resource.

Man-made Resource - Soil:
- Soil is a natural resource that is formed over centuries through the weathering of rocks and organic matter decomposition.
- While soil itself is a natural resource, it can be managed and manipulated by humans through various agricultural practices.
- Therefore, soil is not considered a man-made resource but a natural resource that can be influenced by human activities.

Natural Resource - Plastic:
- Plastic is a man-made material produced from natural resources such as petroleum and natural gas.
- While the raw materials used to make plastic are natural resources, the final product itself is considered a man-made resource.
- Plastic does not occur naturally in the environment and is manufactured through human intervention.

Man-made Resource - Water:
- Water is a natural resource that is essential for all forms of life on Earth.
- While water itself is a natural resource, humans have developed technologies to treat and distribute water for various purposes.
- Therefore, water is a natural resource that can be managed and utilized by humans, but it is not considered a man-made resource.
