Rivet popper hypothesis' to explain the role of species richness for ecosystem healthy was given by

Options

A. David Tiliman
B. Alexander Von Humboldt
C. Robert May
D. Paul Ehrlich

Answer

**Step-by-Step Solution:**

1. **Understanding the Rivet Popper Hypothesis**: The Rivet Popper Hypothesis is a metaphor that compares the species in an ecosystem to the rivets in an airplane. Just as an airplane is held together by many rivets, an ecosystem is maintained by the diversity of species.

2. **Explaining the Importance of Species Richness**: The hypothesis suggests that each species plays a critical role in the functioning of the ecosystem, similar to how each rivet contributes to the structural integrity of the airplane. If too many species are lost, the ecosystem may fail, just as an airplane could fail if too many rivets are removed.

3. **Identifying the Scientist Behind the Hypothesis**: The Rivet Popper Hypothesis was coined by Paul Ehrlich. He emphasized the importance of biodiversity and how the loss of species can impact ecosystem health.

4. **Conclusion**: Therefore, the correct answer to the question is that the Rivet Popper Hypothesis was given by Paul Ehrlich.

**Final Answer**: Paul Ehrlich
