Which Methanogen is present in rumen of cattle ?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Rumen**: The rumen is a part of the stomach in ruminant animals, such as cattle. It is the first chamber of the stomach where fermentation of food occurs, particularly the breakdown of cellulose from plant materials.
