1. habitat pollution
2. introduction of exotic species
3. over exploitation
4. natural habitat destruction

Answer 1

Correct Answer - Option 4 : natural habitat destruction

The correct answer is natural habitat destruction

• Biodiversity is a combined term for life and diversity that refers to the diversity and variability of life on Earth.
• It is measured on the level of genetic, species, and ecosystem level.

• When the natural habitat is not able to support the life which exists in that area it will result in death or destruction of biodiversity.
• This is termed habitat destruction or habitat loss which is caused by the decline in the number of species in an area due to the exploitation and modifying or changing the territory from where that organism belongs or from where they originated.
• The reason for the decrease in biodiversity is overpopulation, global warming, deforestation, and pollution.
• Conservation of biodiversity can be achieved by controlling population, pollution, and deforestation.
• Reason for Loss of Biodiversity:
  • Habitat destruction
  • Invasive Species
  • Over-exploitation of Species
  • Global Warming and Climate Change
