Couple of questions on pull down resistors /analog

I have a photoresistor sensor connected to my arduino, and read it via analogRead.

I have it set up with a pull down resistor as describe at:

I need to setup two light sensors. Can they both share the same pull down resistor? Or do they each need their own 10k pull down resistor?


Draw it out; if they share the same resistor I think that means you've effectively connected the analogue pins together (so separate resistors needed)...
