Does Lloyd have Energy because he’s the Green Ninja, or is he the Green Ninja because he has Energy?

What I mean is, it’s a very fitting power for the Green Ninja. Does it come with the title? Did he get it because of the prophecy? If he wasn’t the Green Ninja, would he have gotten something more akin to Destruction from Garmadon? OR is he the Green Ninja because he happened to have Energy? Could anyone else, say Morro or the other Ninja, have even had a chance even though they don’t have Energy? I haven’t seen the full show I hope this isn’t a stupid question but please I’m kinda confused...
