What organisms apart from algae would have needed to be present to remove carbon dioxide from the early atmosphere? ?

Plants in general I think. 
photosynthetic organisms.

This is what i found on google “lithium and sulfide can react together to form litium sulfide(li2s). when lithium sulfide hydrolyses(breaks down) in air, it releases hydrogen sulfide which is characteristized by a rotten egg odor.” i hope this you for what your looking for
