how to make a sound intensity sensitive led using Arduino UNO??

I want the LED's brightness to be low at low intensity sounds and high at high intensity at high intensity sounds.

Any idea on how to do it??

Sounds just like the potentiometer exercise in this class! Sub out the potentiometer for a microphone, and the AnalogInOutSerial example should work like you describe.
