While seasons one and two aired in the same year, they stretched out the last three seasons. Season three was stretched into 17 months, season four into 26 months (over 2 years), and season five into 31 months (about 3 1/2 years). :shrug: The Powerpuff Girls had more episodes, but finished quicker due to the fact CN aired new episodes of that show regularly, unlike the Eds, which only had a few new episodes aired every few months in it's last seasons.
