What volume of vegetation must a mature Western Gorilla consume daily to meet its energy demands?

Answer

An estimated 40 pounds

The sheer energetic requirements of large primates like the mature Western Gorilla necessitate the consumption of an impressive quantity of plant matter daily, estimated to be around 40 pounds. This large volume is necessary because much of this intake—including stems, leaves, and bark—is high in cellulose and lower in readily accessible sugars compared to fruit, demanding bulk processing to achieve caloric sufficiency.
