Which scientist proposed 'Rivet popper hypothesis' related to biodiversity and Ecosystems ?

Options

A. Tansley
B. Alexandor Von Humboldt
C. Paul Ehrlich
D. David Tilman

Answer

To answer the question "Which scientist proposed the 'Rivet-Popper Hypothesis' related to biodiversity and ecosystems?", we can follow these steps:

1. **Identify the Hypothesis**: The Rivet-Popper Hypothesis is a concept in ecology that relates to biodiversity and the functioning of ecosystems. It suggests that just like an airplane, which relies on all its rivets to function properly, ecosystems depend on the diversity of species to maintain their stability and functionality.

2. **List the Scientists**: The question provides four options:
- Tensley
- Alexander von Humboldt
- Paul Ehrlich
- David Tilman

3. **Recall the Proponent**: The Rivet-Popper Hypothesis was proposed by Paul Ehrlich. He used the airplane analogy to illustrate how the loss of species (like losing rivets from an airplane) can lead to the collapse of the ecosystem.

4. **Select the Correct Answer**: Based on the information gathered, the correct answer to the question is Paul Ehrlich.

**Final Answer**: The scientist who proposed the 'Rivet-Popper Hypothesis' is Paul Ehrlich.
