Final answer:
Vineyards and grapes are the natural resources that support Italy's wine production, historically significant as part of the Roman economy with exports in amphorae.
Step-by-step explanation:
The natural resources that support Italy's wine production are vineyards and grapes. This is because the cultivation of grapes is essential for the production of wine, and Italy's favorable climate and fertile soil provide excellent conditions for vineyards.
Historically, agriculture played a vital role in the Roman economy, with Italy specializing in high-value products like wine and olive oil, which were then exported throughout the Mediterranean in amphorae.
