Question

Which of the following hypothesis suggests that ecosystems are like aeroplanes where flight safety (ecosystem functioning) may or may not be compromised, depending upon which species are being lost?

विकल्प

• Gaia hypothesis

• Gause's exclusion hypothesis

• Quantum hypothesis

• Rivet popper hypothesis

Answer 1

Rivet popper hypothesis

Explanation:

According to the Rivet Popper theory, ecosystems are similar to aeroplanes, where flight safety (ecosystem functioning) may or may not be affected.
This hypothesis considers the environment to be an airframe and the species to be rivets that hold everything together.
If every passenger starts popping rivets to take home (resulting in species extinction), it may not affect fight safety at first (proper ecosystem functioning), but as more and more rivets are removed over time, the plane will become dangerously weak, especially if key rivets (keystone species) are removed.
