The Android kernel is a variation of the Linux kernel. It's not similar to Linux. It is Linux (or a subset of Linux with some special extensions).
Every app uses kernel resources, whether it is in a runnable state or not. This is true of Linux, and of UNIX, which Linux is patterned after.
Whether that makes a perceptible difference is another question, but it does use something. A lot of those background processes are also doing something. For example, WeatherBug. One might want to turn it off for a while.
