Detailed explanation-1: -Habitat fragmentation is defined as the process during which a large expanse of habitat is transformed into a number of smaller patches of smaller total area isolated from each other by a matrix of habitats unlike the original (Fahrig, 2003).

Detailed explanation-2: -Fragmentation happens when parts of a habitat are destroyed, leaving behind smaller unconnected areas. This can occur naturally, as a result of fire or volcanic eruptions, but is normally due to human activity. A simple example is the construction of a road through a woodland.

Detailed explanation-3: -The separation of an ecosystem into small pieces of land is called habitat fragmentation.

Detailed explanation-4: -Habitats can also be degraded when natural process they depend on, such as fire or flooding, are altered by human activity. Habitat fragmentation occurs when large blocks of habitat are cut into smaller pieces by development such as roads or housing.

Detailed explanation-5: -Destruction and degradation of natural ecosystems are the primary causes of declines in global biodiversity (1, 2). Habitat destruction typically leads to fragmentation, the division of habitat into smaller and more isolated fragments separated by a matrix of human-transformed land cover.
