New Tracks in logic always seem to have the same two reverb buses on them ? What gives?

Hi I’m new to Logic and have been learning to use buses for effects . I’ve come to notice  that every time I open a track there are always two buses Already on it  usually two reverbs  a small room and some other.

Is this on every track whatever . Is it ok to move or modify them to taste  and is it just a feature to give most tracks a tiny bit of air instead of just sounding dry .

thanks for any input /help.  Best regards Paul
