Are you new to Android? I had this same confusion when I first moved to Android.. Because it runs on a Linux basis it works differently..
2 things to consider.
1, Android will hold programmes in memory but in a suspended state, not using any resources until they are called for from the kernel.
2, with Linux based OS empty memory is wasted memory. (refer to point 1 above!)
Don't try to kill things that the phone need to have running in the background it will waste resources and battery!
