I think we can develop a theory for "why chaotic systems develop equilibrium" and I think it would start with concentrations of energy sources. If there is a lot of sediment with nutrients and energy being buried on the sea floor -- it's LIKELY that some organism will exploit it eventually.
It's interesting to look at (if I remember correctly) the Pleistocene epoch, where for about 50 million years there was no bacteria that broke up and digested falling trees. So we have a lot of coal from this epoch for this very reason.
EVENTUALLY, bacteria that converted wood pulp evolved and we are not a planet layered in fallen trees.
But there's also no guarantee -- hence the runaway "Oxygen pollution" that almost lead to the earth freezing over. The worms churning the see floor were LIKELY but not necessarily inevitable.
There also seems to be a need for a dynamic environment without too many drastic swings for life to keep evolving.
