Explanation

To determine which of the following is not a natural resource, we need to analyze each option based on the definition of natural resources. Natural resources are materials or substances that occur in nature and can be used for economic gain or to sustain life, without human intervention.

1. **Identify the options**: The options given are:
- Mango tree
- Snake
- Wind
- Wooden house

2. **Analyze each option**:
- **Mango tree**: This is a plant that grows naturally in the environment. It is considered a natural resource because it provides fruit and other benefits without human intervention.
- **Snake**: This is a living organism that exists in nature. It is also considered a natural resource as it exists without human influence.
- **Wind**: Wind is a natural phenomenon that occurs in the environment. It is a natural resource as it can be harnessed for energy (like wind turbines) and is not created by humans.
- **Wooden house**: This is a structure made from wood, which is a natural resource, but the house itself is a product of human construction. It does not exist in nature as a house; it is made by humans using natural resources.

3. **Conclusion**: Based on the analysis, the wooden house is the only option that is not a natural resource because it is a man-made structure.

Therefore, the answer is **wooden house**.
