How is habitat fragmentation related to biodiversity loss?

Habitat fragmentation is the process in which a large habitat area is reduced into several small patches that reduce the area of habitat for species that live there.

Habitat loss can occur naturally like jungle fire, volcanic eruptions or artificially by human-made fragmentation through cutting of trees for making roads.

Habitat fragmentation leads to biodiversity loss because it reduces the availability of suitable habitats for organisms. Animals like tigers, leopards require a large habitat for their living so habitat fragmentation affects their survivability rate adversely.  

Therefore habitat fragmentation is directly related to biodiversity loss.
