Final answer:
The Meakambut obtain their food and shelter through a gatherer-hunter lifestyle, involving hunting, gathering, and the use of temporary shelters, while relying heavily on extensive knowledge of their environment.
Step-by-step explanation:
The Meakambut obtain food and shelter by employing a lifestyle consistent with gathering-hunting societies. Their sustenance comes primarily through hunting, gathering, and exploiting natural resources, which involves gathering fruits, nuts, berries, and roots as well as hunting and trapping wild animals and fishing. Instead of building permanent structures, they utilize temporary shelters which are more suited to their nomadic lifestyle. The Meakambut's way of life is a direct connection to our hominin ancestors, who, for millions of years, practiced a similar way of living to survive in various environments. This lifestyle requires extensive knowledge of the environment, including plant and animal behavior, to efficiently gather and hunt for food. Like other gatherer-hunters, the Meakambut live a highly mobile life, moving with the seasons and availability of resources.
