What's a word that means two things work together and add to each other to make them better? I have a specific word that I want in the back of my mind but I can't remember what it is.
My first thought was complement, but Gary beat me to it. This would particularly apply to the usage of "providing all that is necessary to make a whole".
If not that, I suggest reinforce, in the sense of "to strengthen, by adding materials", but applied to something other than physical objects.
Are you thinking of symbiotic/symbiosis?
