Question:

According to the "rivet popper hypothesis," why is the loss of certain species critical for the functioning of an ecosystem?

Options:

Loss of certain species affects flight safety in airplanes.

Loss of certain species affects the quality of life for humans.

Loss of key species can lead to the collapse of major ecosystem functions.

Loss of certain species does not impact ecosystem health significantly.

Correct Answer:

Loss of key species can lead to the collapse of major ecosystem functions.

Explanation:

c) Loss of key species can lead to the collapse of major ecosystem functions.

According to the "rivet popper hypothesis," the loss of key species can lead to the collapse of major ecosystem functions.

In the analogy, key species are likened to rivets on the wings of an airplane. Just as certain rivets are crucial for maintaining the structural integrity of an airplane, key species in an ecosystem play essential roles in supporting vital ecological processes and interactions. These species may be involved in pollination, seed dispersal, nutrient cycling, predation, or other critical functions.

If these key species are lost from the ecosystem (similar to popping rivets from the airplane's wings), it can disrupt the delicate balance of ecological interactions and processes. As more key species are lost, the ecosystem's stability and resilience become increasingly compromised. Ultimately, the loss of critical species can lead to the collapse of major ecosystem functions, impacting not only the ecosystem itself but also the services it provides to humans and other organisms.

This highlights the importance of maintaining biodiversity and protecting key species within ecosystems to ensure their proper functioning and long-term health. The "rivet popper hypothesis" serves as a reminder of the potential consequences of species loss and the significance of preserving the intricate web of life that sustains us all.
