Answer :
The element "large ore deposits" is the option that is NOT necessary to support life.
Here's why:
1. Large ore deposits are not essential for supporting life. They are valuable resources for various industries and economic activities but are not directly related to the basic requirements for life such as air, water, nutrients, and a suitable environment for organisms to thrive.
2. Vegetation/plant life is crucial for producing oxygen, providing food, regulating climate, and supporting diverse ecosystems.
3. A healthy watershed is essential for supplying clean water for drinking, irrigation, and sustaining aquatic life.
4. Correct pH levels (not too low) are important for maintaining proper chemical balance in soil and water, which in turn supports plant growth and other organisms in the ecosystem.
In summary, while large ore deposits have their importance, they are not a necessity for supporting life compared to the other options provided in the question.
