Mutually beneficial (9)

Ross

I believe the answer is:

symbiotic

'mutually beneficial' is the definition.
(I've seen this in another clue)

This is all the clue.

(Another definition for symbiotic that I've seen is " Mutually beneficial".)

I've seen this clue in the Wall Street Journal and The Guardian.
