Final answer:
The Biligiriranga Hills connect the Eastern and Western Ghats, providing an ecological bridge between the two ranges that are crucial for biodiversity and habitats for various species.
Step-by-step explanation:
The correct answer is a. the Biligiriranga Hills:
These hills serve as a bridge between the two prominent mountain ranges in India, connecting the biodiversity and ecological aspects of both regions.The Western Ghats, reaching heights of up to 8,000 feet but averaging around 3,000 feet, are known for their rich biodiversity, which includes an extensive range of flora and fauna. These highlands are also known for their sprawling coffee and tea estates, contributing to India’s agriculture and economy.
On the other hand, the Eastern Ghats might not be as towering but share physical similarities with their western counterparts. Both are separated by the Deccan Plateau and are key to India's ecological balance, providing habitats to numerous species such as tigers and Asian elephants, especially around the Chota-Nagpur Plateau that receives significant monsoon rains averaging 52 inches a year.The Biligiriranga Hills stand distinctively at the confluence of these two mighty ranges, reflecting the convergence of distinct ecosystems and enabling wildlife corridors that are vital for the movement and genetic exchange among animal species.
