I don't think anyone would expect that - but the goal in space is not to replicate as much of the Earth biospheres variety in a closed system, but to feed a couple people for as long as possible (but not necessarily indefinitely) with the materials at hand.

I think a vat-grown culture of highly nutritious fungi (or algae or whatever, I'm no expert and I don't pretend to have even an SF writer's level of understanding of the subject) would be a much more viable solution.
