Detailed explanation-1: -October 2021) Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism’s preferred environment (habitat), causing population fragmentation and ecosystem decay.
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.
Detailed explanation-3: -Habitat fragmentation involves the splitting of natural habitats and ecosystems into smaller and more isolated patches. It reduces the availability and the suitability of adjacent areas for wildlife.
Detailed explanation-4: -In addition to loss of habitat, the process of habitat fragmentation results in three other effects: increase in number of patches, decrease in patch sizes, and increase in isolation of patches.
Detailed explanation-5: -The example for the fragmentation is the Amazon rainforest that leads to extinction of species which is being cut and cleared for soybean cultivation for conservation to grassland for raising beef cattle. This is the fragmentation of the land which leads to population declines.
