Answer:
The number of habitats falls below a critical level.
Explanation:
The possible reason for extinction is that the number of habitats falls below a critical level. This makes it impossible for organisms to survive.

- The resources and other materials that ensures the survival of an organism are made available in the habitat.
- When a habitat begins to thin out and can no longer support organisms, then extinction will ensue.
