Detailed explanation-1: -Habitat fragmentation occurs when large blocks of habitat are cut into smaller pieces by development such as roads or housing. The remaining blocks of habitat may be too small to sustain populations of a number of species and the fragmentation often results in barriers to species movement.

Detailed explanation-2: -Habitat fragmentation The breaking apart of habitat into several smaller pieces. Habitat fragmentation results in both habitat loss and fragmentation per se. Habitat loss A change to an area that prevents a species from living there (e.g., conversion of forest to crop field).

Detailed explanation-3: -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-4: -Habitat loss generally refers to the decrease in the spatial extent of natural habitat, including forest, grassland, desert, and wetlands [1, 2], whereas habitat fragmentation per se is the breaking apart of habitat after controlling for habitat loss [3].

Detailed explanation-5: -Habitat destruction and fragmentation is a process that describes the emergences of discontinuities (fragmentation) or the loss (destruction) of the environment inhabited by an organism.
