eli5 If you cut down a perfectly healthy tree, at what point would the tree be considered “dead”?

Question

I would assume the fallen tree would have enough nutrients to sustain itself for a while and would eventually start dying. Most living things are dying until they’re dead but what exactly is the threshold from dying to dead for a suddenly severed tree?

I’ve pushed over trees and found that one root has been keeping it on life support. Ild say when it’s chopped from the roots making it unable to take up nutrition.
