Question

What civilization relied heavily on hunting and fishing to gather food

Answer 1

The civilisation of the Algonquian people relied heavily on hunting and fishing to gather food.

Explanation:

After breaking from their ancestors, the Algonquian tribes moved to the east and inhabited the coasts of the Atlantic Ocean. This civilisation in the early history of North America is known for having the least interest in producing their own food.

This habit of theirs is also referred back to the lack of means of producing food that they faced.
