Explanation:

The Indomalaya ecozone is one of Earth’s eight ecosystems. It covers most of South and Southeast Asia and parts of East Asia. This area was originally known as the Oriental Region by most scientists (especially biogeographers). Indomalaya extends from Afghanistan to Pakistan through the Indian subcontinent and Southeast Asia to southern China, and through Indonesia toward Java, Bali, and Borneo. Indomalaya borders Australasia to the east and both are separated by the Wallace Line. Indomalaya also includes the Philippines, lowland Taiwan, and the Ryukyu Islands of Japan.The Indian Subcontinent covers most of India, Pakistan, Bangladesh, Nepal, Bhutan, and Sri Lanka. The Himalayan Range, along with Hindu Kush, Karakoram, and Patkai Ranges, bind the region to the north, northwest, and northeast. These ranges were formed 45 million years ago when the Indian subcontinent collided with Asia. These ranges (excluding Patkai) border the temperate Palearctic ecozone.
