In The Giver, how is work distributed and where do they get thier food? For example, how would potato be chips made?

The Giver is a communist society, where work and resources
are shared.  There is no money, and everything a person needs is provided.  People do
not make choices as to what food they eat, and I doubt potato chips would be available. 
Since the community is engineered for sameness and it is important for everyone to be
healthy, snacks like the apple Jonas keeps are more likely to be provided.  Processed
foods like potato chips would be avoided.   Any food that is grown or manufactured would
be produced by those people deemed by the community most fit to do the work, but
otherwise the process would be basically the same as ours.
