There is no "task manager" in Android.

There is the "recent tasks" list, brought up by a long-press on the
HOME button (Android 1.x and 2.x) or a dedicated soft button (Android
3.x).

There is the "Running" tab of the Manage Applications screen in
Settings on newer versions of Android.

Anything else is a third-party application, either from a device
manufacturer or an app you installed yourself.

You cannot "terminate an application" in the recent tasks list. You
can stop an application via the Running tab, which should cause its
process to end.

The "recent tasks" list has nothing to do with processes. If an
application has a running activity or service, it should appear in the
Running tab.
