Final answer:
The Urus were a group of fishermen living around Lake Titicaca, known for maintaining a subsistence lifestyle that revolved around the resources of the lake.
Step-by-step explanation:
The Urus were a group of people known for their unique lifestyle centered around Lake Titicaca. More specifically, they are recognized as fishermen and people who have traditionally lived in the Lake Titicaca region, making their living from the resources that the lake and its surrounding area provide. While the larger Tiwanaku Empire that existed on the shores of Lake Titicaca is well documented for its extensive agricultural practices, complex social organization, and sophisticated ceremonial rituals, the Urus people maintained a distinct presence in the region, largely focusing on fishing and maintaining a subsistence lifestyle even after the decline of larger pre-Columbian civilizations like the Tiwanaku. Other societies, such as the Nazca and the Moche, thrived under different conditions but did not form the basis of the Urus' way of life.
