Removing Google & Facebook services from iOS.

Hello.

Is it possible to completely remove Google and or Facebook services from iOS? ...any version of iOS.

If so,...

with which version/s of iOS can I do this?

If no,...

1. How far can I remove, disable or block Google & Facebook services from iOS devices that I own?
2. With which version of iOS can I remove, disable or block them the most?
3. How are these services inseperable from/intergal to iOS? ...any version of iOS.

Thanx,
