A) The correct answer is 33%.

Endemic species are restricted to a given area for various reasons like some special requirements for optimum growth, soil and other environmental conditions etc. India ranks 47%, Australia - 80% and Hawaii- 82%.

Occurrence of endemic species in South America and Australia is due to continental drift. Continental drift is the gradual movement of the continents across the earth's surface. Therefore, the correct answer is option B.

• Habitat destruction occurs when natural habitats are no longer able to support the species present, resulting in the displacement or destruction of its biodiversity.
• The growth of the human population has impacted the planet and affected biodiversity. The need for food, space and raw materials has resulted in the destruction of habitats and pollution.
  
• Introduction of invasive species causes harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.

The variety of plants which are found in a particular region at a time is known as flora. This flora includes all the type of plant life and can be organised into different categories as native plants, agricultural, horticultural, floral and weeds. The flora of a particular region at a time is documented and then published. This helps to maintain a record of the type of plants in the region which existed at a particular time.
