A. Habitat destruction; developed countries B. Habitat destruction; developing countries C. Biological uniformity; developed countries D. Biological uniformity; developing countries

Answer 1

Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or die, thereby reducing biodiversity and species abundance.Habitat destruction through human activity is mainly for the purpose of harvesting natural resources for industrial production and urbanization. Clearing habitats for agriculture is the principal cause of habitat destruction. Other important causes of habitat destruction include mining, logging, trawling, and urban sprawl. Habitat destruction is currently ranked as the primary cause of species extinction worldwide.The destructive environmental changes include more indirect factors like geological processes, and climate change,introduction of invasive species, ecosystem nutrient depletion, water and noise pollution and others. Loss of habitat can be preceded by an initial habitat fragmentation.

Hence ( B) part is a correct answer
