Which specific spongy plant tissue is highlighted as a particularly important nutrition source for the Western Gorilla?

Answer

The pith

The pith, which is defined as the spongy tissue residing in the center of plant stems, represents a crucial source of nutrition for the Western Gorilla. While leaves, stems, and seeds form the foundation of their intake, the pith is singled out for its significant nutritional contribution, especially when they are relying heavily on structural components rather than easily accessible sugars found in fruit.
