I believe it's in the room near the end of the temple with the redeads. Din's fire is the best way to get it. All you must do is burn down the walls that close in on you approach the blue studded chest, and open it for the key.
Beat a boss and a chest will appear with a bow in it.
You collect the Longshot in the room of the Water Temple after defeating the sub-boss, "Dark Link."
Play through the temple. You do know there are literally hundreds of walkthroughs on YouTube.

It is in the Fire Temple, on the 4th floor. Consult a strategy guide for more details. Naw, duh.l'v'l B-)
move around
If you're talking about dodongo's cavern, you fall down a hole. In the actual fire temple, then you jump onto the rock that has some holes on the ground.
Electrocute him.
Ghoma, took me 3 minutes :D
you have to blow to enter and for boss you have to get boss key
Put a bomb in the center of the room.
It's on the map.
