Why is my colour ink almost as empty as my black ink despite only printing black and white?

I’ve noticed recently that after printing with my Canon MX870 multifunction printer that all of my ink levels seemed low, even the color ink. I say this because when I first started printing with this printer, I was copying and printing items that were strictly in black and white. I noticed that after printing several items, not only was my black ink lower which was obvious, but my color ink was dropping too.

Another interesting issue I have is that I have three color cartridges: cyan, yellow, and magenta and two black cartridges: one small and one big. For some reason the smaller black ink cartridge is still completely full when observing on the ink menu. Any reason for these situations occurring?
