[Avodah] Blessing before and after eating

[Galsaba at aol.com]

I am not sure how to define if a Mitzvah is from Rabanan or Torah. For 
example: According to Berachot daf 21, Chazal learned from Kal Vachoner that Beracha 
before eating is from Torah, although the Torah does not write it BeFeirush.  
In this case, when Chazal learned, would it be Mitzvah DeRabanan? or from 
DeOrayta? Another example is "Tuma'at Of Tahor" it does not say BeFeirush in the 
Torah.
Is there any different in the applications between those that were written 
Beferush in the Torah to those that were leaned by Chazal?
 
Thanks,
