(i) Producer
(ii) Primary consumer
(iii) Secondary consumer
(iv) Tertiary consumer

Options

A. i and ii
B. ii only
C. ii and iii
D. iv only

Answer

To determine at which trophic level Denny functions in the food chain after eating spinach, salad, and mutton curry, we can analyze the food chain step-by-step.

### Step-by-Step Solution:

1. **Identify the Food Items**: Denny ate spinach, salad, and mutton curry.
- Spinach and salad are plant-based foods.
- Mutton curry is derived from an animal (goat).

2. **Classify the Food Items**:
- **Spinach and Salad**: These are producers because they are plants that produce energy through photosynthesis.
- **Mutton**: This comes from an animal that likely fed on plants (herbivore), making it a primary consumer.

3. **Determine Denny's Role**:
- Denny is consuming both plants (spinach and salad) and an animal (mutton).
- By eating spinach and salad, Denny is acting as a primary consumer because he is consuming producers.
- By eating mutton, Denny is acting as a secondary consumer because he is consuming a primary consumer (the goat).

4. **Conclusion**: Since Denny consumes both producers (spinach and salad) and primary consumers (mutton), he functions at two trophic levels:
- Primary Consumer (for the plants)
- Secondary Consumer (for the mutton)

5. **Final Answer**: Therefore, Denny functions at both the primary and secondary consumer levels in the food chain.
