I've often talked about how life has evolved on four specific paths that can be called food in / waste out. Two paths or options to food in. Two paths or options to waste out.

The four options are
1 Nurturing* taken in.
2 Non nurturing (waste) blocked out.
3 Nurturing held in
4 Non nurturing (waste) excreted out.

*Nurturing is anything that helps that organism survive in that
environment.

No matter how life evolved, each step is one or more of these
4 basic options or paths of natural selection.

I now suggest that this has a fundamental biological basis.
Food in relates to metabolism
Waste out relates to replication.

1 Nurturing taken in,
3 Nurturing held in.
would both relate to metabolism

As far as I can imagine what you mean, you made a mistake by including
"(waste)" in the line describing option #2.

Otherwise I can hardly complain about how deeply you have descriptively
boiled down the logic of life.
