Since photosynthesis is a process that uses co2 and cellular respiration is the process to create co2, if there aren’t any processes of cellular respiration to create the co2 needed in the photosynthesis, it wouldn’t happen.
it's very practical, because it's on base 10, so conversion between stuff like meters to kilometer is always just a multiplication with 10 to some power
like 1 km = 1000m (10³m)
or 1 m = 10^-3km = 0.001km
same reason for other SI units.
except time, that's base 60, or 12, or 24. that's more complicated, but there isn't any real competition
