The characteristic of little available food is more closely associated with Sparta. Spartans had a system that relied on the agricultural labor of the helots, and as a result, their economy and society were structured around maintaining their military strength rather than agricultural abundance for leisure or trade, which could lead to food shortages during times of conflict.
Athens, on the other hand, had a diverse economy that included trade and a more stable food supply due to its access to the sea and trade routes.
Thus, the correct answer would be Sparta.
