Which river passes through Seshachalam biosphere reserve?

Solution (By Examveda Team)

The Seshachalam Hills, together with the Erramala Range to the north, vary in elevation from 1,300 to 4,500 feet (400 to 1,370 metres). The hillslopes have only a thin forest cover because of scanty rainfall. Tributaries of the Penneru River drain the region.
