Bacteria living in the intestine of herbivores help in the digestion of

Options

A. cellulose
B. proteins
C. fats
D. vitamins

Explanation

**Step-by-Step Solution:**

1. **Identify the Organism**: The question refers to bacteria living in the intestines of herbivores. Herbivores are animals that primarily eat plants.

2. **Understand the Role of Bacteria**: These bacteria play a crucial role in the digestive process of herbivores. They help break down complex plant materials that the herbivores themselves cannot digest.

3. **Key Component of Plant Cell Walls**: The primary component of plant cell walls is cellulose. This is a complex carbohydrate that provides structural support to plants.

4. **Digestive Capability**: Unlike humans, herbivores have specialized bacteria in their intestines that can break down cellulose into simpler sugars that can be absorbed and utilized by the herbivore.

5. **Conclusion**: Therefore, the bacteria in the intestines of herbivores help in the digestion of cellulose, which is a major component of the plants they consume.

6. **Final Answer**: The correct answer is cellulose.
