Subject: Why is it that bread mold grows quicker in dark, wet and warm conditions?

I've researched for weeks and have learned a lot about molds, rhizopus, etc. 
but nothing has told me WHY mold grows quicker in warm, dark, moist conditions.
I've set up the experiment and found it to be true, but don't understand why. 
Any help would be greatly appreciated. Thanks
