What is a possible reason for extinction? The number of habitats falls below a critical level.
Too many resources
Less competition
Less number of new predators

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.

A habitat is the dwelling place of living organism in an ecosystem. 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.
