@Haleh idk if you still need this, but both should still work at the end of the day. When you put the plant life into the domain, you are left with Cannot Survive without atmospheric carbon. If we choose group three (without) we then negate, sufficient either survive or without atmospheric carbon. That results in giving us /Atmospheric Carbon -> /Survival. The (without) is describing the atmospheric carbon which is positive, so I negated that and put it in the sufficient. The remaining thing, cannot survive I just put into the necessary. If you chose the opposite and let's say we chose cannot survive and negated that and put it into the sufficient, then it becomes Survive -> C. This time the (without is describing the cannot survive and so I negated that, and then the remaining atmospheric carbon is put into the necessary. I hope this helps!
