What type of micro-organisms digest cellulose carbohydrate present in the grass food of ruminant?

Explanation

**Step-by-Step Solution:**

1. **Understanding Ruminants**: Ruminants are animals that primarily eat grass and other plant materials. Examples include cows, sheep, and goats.

2. **Identifying the Carbohydrate**: The main carbohydrate found in grass is cellulose. Cellulose is a complex carbohydrate that is difficult for many animals to digest.

3. **Role of Micro-organisms**: Ruminants have a special adaptation that allows them to digest cellulose. This adaptation involves the presence of certain micro-organisms in their digestive system.

4. **Types of Micro-organisms**: The specific type of micro-organisms that help in digesting cellulose in ruminants are known as cellulose digesting bacteria. These bacteria break down cellulose into simpler sugars that the ruminants can absorb and utilize for energy.

5. **Conclusion**: Therefore, the type of micro-organisms that digest cellulose carbohydrate present in the grass food of ruminants are cellulose digesting bacteria.

**Final Answer**: Cellulose digesting bacteria.
