Answer:
It depends on the context.
Explanation:
In an economic and social context, the aztecs relied the most on tributes from sorrounding tribes that were under their dominion. These tribes tributed the aztecs many commodities, like feathers, crops, spices, and metals.
In a religious context, the aztecs mostly relied on human sacrifice to please their gods. The Aztecs sacrificed thousands of people per year, taken from enemy tribes as prisoners of war, but also from their own population. Sometimes, even priests sacrificed themselves to the gods, on top of the pyramids.
