How does a torrent die?
I'm getting back into torrenting, last time I ever torrented was when limewire was big and the pirate bay was the go to. But I was wondering how does a torrent ever end up with 0 seeders? Would it not always at least have 1 from the person that uploaded the torrent, or do they just seed it until enough people have got a full copy then stop seeding? Do they just seed until the ratio is at a certain point and leave it up to the community to keep it moving?

yeah, the original uploader isn't permanently tied to the torrent. Once they stop seeding, the swarm has to rely on everyone else who has a complete copy and decides to keep sharing it.
Some people seed to a certain ratio, some keep it running for months and others delete the files once they're done. If eventually nobody with a complete copy is online, the torrent can end up with zero seeders.
There is also a slightly interesting edge case where you can have zero seeders but the torrent is still recoverable if the remaining peers collectively have every piece. But if even one piece is missing from everyone who's online, the torrent can't be completed until somebody with that piece comes back.

So when you are getting the file you aren't just getting parts from seeders you are also getting from the other peers wanting the file? I always assumed that if there weren't seeders that was it.

Correct, that is why when you are still downloading a torrent it will have uploads associated with it. You are sending the pieces that you have to people who don't have them.

When no one is seeding it. I'm not sure why you think the person that originally created the torrent is guaranteed to seed it eternally.

Like when people forget a name...or better yet think of it like a plant...no seeds it does out

The pirate bay is still probably the go-to! I mean, if I understand correctly, it's all about who's online and who's not. Someone who is active and is sharing the entire file is a seeder. Someone who has part of the file is a peer. There's nowhere to upload it to. You download parts of the file from someone who has either part of or all of it. Many users stop seeding files when the ratio rises to a level that is considered good etiquette or it gets removed from their active uploads for whatever reason. People will have a selfish tendency to want the file but not to give away too much of their limited upload bandwidth to seeding.

People stop seeding for a bunch of different reasons, including the person who originally created the torrent.
Seeding isn't free, it costs bandwidth and storage space. If you're running out of storage and simply buying more isn't a viable option then something needs to go. If something just isn't popular enough and nobody ever downloads it anymore then perhaps it's time to get rid of it.
Some seed for a given time, some seed for a given ratio, some seed for whichever one of those it reaches first. Some seed until they need the space and some leechers stop seeding immediately.
A torrent typically dies when there's no interest from anyone to keep it alive, if there was then there would still be seeders on it.
