David Tilman's experiment is related to ?

Options

A. Role of species diversity in ecosystem stability.
B. Role of dominant species in stability of ecosystem.
C. Role of human being in maintaining of ecosystem.
D. More than one option is correct .

Answer

**Step-by-Step Solution:**

1. **Identify the Experiment**: David Tilman's experiment is primarily focused on understanding the relationship between species diversity and ecosystem stability.

2. **Background Knowledge**: Before Tilman's work, the connection between species diversity and ecosystem functioning was not well understood. His research aimed to clarify this relationship.

3. **Conducting the Experiment**: Tilman conducted experiments in various plots where he varied the number of species present. He observed how these variations affected the ecosystem's performance.

4. **Key Findings**:
- He discovered that ecosystems with higher species diversity exhibited less year-to-year variation in productivity. This means that more diverse ecosystems were more stable over time.
- Additionally, he found that increased species diversity was associated with higher overall productivity in these ecosystems.

5. **Conclusion**: Based on his findings, the experiment is related to the role of species diversity in ecosystem stability. This means that ecosystems with a greater variety of species tend to be more resilient and productive.

6. **Answer the Question**: Therefore, the correct answer to the question "David Tilman's experiment is related to?" is the role of species diversity in ecosystem stability.
