Use Pal Park which opens at the end of the game when you have beat the Pokemon league which is south of sandgem beach.
You cannot "trade" pokemon between Pokemon FireRed and Pokemon Pearl. Instead, pokemon from Pokemon FireRed Version can be transferred to Pokemon Pearl via Pal Park.
trade from firered or leafgreen
Get in FireRed and migrate. Or trade from a friend.
You Can't do that. You can migrate Pokemon from firered but once you do they can't go back.
You can't catch it at Pokemon Pearl, you'll have to Transfer it from LeafGreen/FireRed or trade it with SoulSilver/HeartGold
There are no scythers in the wild in Pokemon Pearl. You have to either transfer it from FireRed, or trade it from one of the other DS games.
You must migrate from FireRed/LeafGreen or trade from Platinum.
no no You can migrate Pokemon from any GBA game to Diamond or Pearl, but not trade. you still get the Pokemon on diamond but you will not put new Pokemon in red
No. But you can trade from FireRed, LeafGreen, Sapphire, Ruby or Emerald to Diamond, Pearl or Platinum
Either Trade From Another That Has It, Action Replay Pokemon Modifier , Or Migrate From FireRed Or LeafGreen.

It's not possible. After a Pokemon is migrated to diamon pearl or platinum, it can't be brought back
