Where did the Inca Indians gather food?

The Inca Empire extended as far north as Ecuador and Argentina to the south, and included Bolivia and Peru. The Incas were knowledgeable agriculturalists, domesticating and developing many different plants such as maize (corn) and potatoes for food and other plants for medicinal purposes. As world-class engineers, they terraced mountainsides, incorporating proper drainage, methods of irrigation, and by learning the importance of fertilizers, soil conservation. In Peruvian valleys and elsewhere, they artificially reconstructed the surface soil for growing crops

Among the wild animals they domesticated for food is the little rodent, the "cuy." We also know it as the "guinea pig." And from the indigenous American camel called the "guanaco," they developed two breeds for their wool and meat, the "llama" and "alpaca."

Wild fowl, Freshwater Fish and seafood were also consumed.

So where did Inca Indians gather food? The answer is: From everywhere and anywhere they could grow it.
