Question

9/10 which of the following is not a major cause of extinction? habitat loss natural selection over-exploitation pollution

Explanation:

To determine the non - major cause of extinction, we analyze each option:

• Habitat loss: It is a well - known major cause of extinction as it destroys the living spaces of species, making it hard for them to survive and reproduce.
• Natural selection: Natural selection is a process of evolution where organisms better adapted to their environment tend to survive and produce more offspring. It is a slow, natural process that helps species adapt and is not a direct cause of extinction on a large scale like human - induced factors.
• Over - exploitation: Activities like overfishing, overhunting, etc., can lead to the rapid decline of species populations and is a major cause of extinction.
• Pollution: Pollution (such as air, water, and soil pollution) can harm organisms, disrupt ecosystems, and contribute to species extinction.

Answer:

B. Natural selection
