Which South American country is known for its bananas, but has petroleum as its main economic product?

Ecuador is indeed known for both its banana production and its economic reliance on petroleum. The country is one of the largest banana exporters in the world, highlighting its significance in the global banana market. However, despite this agricultural prominence, petroleum is Ecuador's main economic product, contributing significantly to the country’s exports and overall economy. The petroleum industry plays a crucial role in generating revenue for the government and driving economic growth.

While Colombia and Brazil are also involved in significant agricultural production, including bananas, they do not have the same level of emphasis on petroleum as a primary economic product in comparison to Ecuador. Venezuela, on the other hand, is primarily known for its oil exports, which overshadows its agricultural exports like bananas. Thus, the identification of Ecuador as the country known for both its banana production and petroleum as its primary economic driver is accurate.
