How did the Inca use local resources to build their empire?

The Incas used locally available material to sustain the empire.

Explanation:

The Inca people were dependent locally available food sources in the form of edible roots, potatoes, maize, guinea pigs, llamas, dried fish, etc. They have sought methods to transform the barren land into more fertile and ideal for cultivation in South America.

They used stone and wood for construction purposes.
