Mr. X is eating curd/yoghut. For this food intake in a food chain he should be considered as occupying

Options

A. first trophic level
B. second trophic level
C. thrid trophic level
D. fourth trophic level.

Explanation

To determine the trophic level occupied by Mr. X when he is eating curd/yogurt, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Food Source**: Mr. X is consuming curd/yogurt. This is a dairy product.

2. **Understand the Origin of Yogurt**: Yogurt is produced from milk, which is obtained from cows. Therefore, we need to consider the trophic level of cows.

3. **Determine the Trophic Level of Cows**: Cows are herbivores; they feed on grass and other plants. In a food chain, plants are considered producers and occupy the first trophic level.

4. **Identify the Trophic Level of Cows**: Since cows feed on plants (producers), they are classified as primary consumers. Thus, cows occupy the second trophic level.

5. **Determine Mr. X's Trophic Level**: Since Mr. X is consuming yogurt (which comes from cows), he is consuming a product derived from a primary consumer. Therefore, Mr. X occupies the next trophic level above cows.

6. **Conclusion**: Mr. X, by consuming yogurt, is classified as a secondary consumer, which places him at the third trophic level.

### Final Answer:
Mr. X occupies the **third trophic level**.
