The carnivorous plants live in water logged or boggy habitats which are

Options

A. deficient in nitrates
B. deficient in sulphites
C. deficient in oxygen
D. deficient in many salts.

Answer

### Step-by-Step Solution:

1. **Understanding Carnivorous Plants**:
- Carnivorous plants are specialized plants that derive nutrients by trapping and consuming other organisms, primarily insects. They are adapted to grow in nutrient-poor environments.

2. **Identifying the Habitat**:
- These plants typically thrive in waterlogged or boggy habitats. Such environments are characterized by poor drainage and high moisture content.

3. **Nutrient Deficiencies in Boggy Habitats**:
- In boggy habitats, the soil is often deficient in essential nutrients. The key deficiencies include:
- **Nitrates**: Essential for protein synthesis and overall plant growth.
- **Sulphites**: Important for amino acids and proteins but not as critical as nitrates for these plants.
- **Oxygen**: While oxygen is crucial for respiration, the waterlogged conditions can lead to low oxygen availability in the soil.
- **Many Salts**: These habitats may lack various mineral salts necessary for plant health.

4. **Role of Nitrogen in Carnivorous Plants**:
- Since these plants are often nitrogen-deficient, they have evolved mechanisms to trap insects to supplement their nitrogen intake. This adaptation is crucial for their survival in nutrient-poor environments.

5. **Conclusion**:
- Among the options provided, the most significant deficiency that carnivorous plants face in their boggy habitats is the lack of nitrates. Therefore, the correct answer is that carnivorous plants are deficient in nitrates.

### Answer:
The correct option is: **Deficient in nitrates.**
