### Step-by-Step Solution:

1. **Understanding Saprozoic Feeding Habit**:
- Saprozoic feeding refers to the consumption of decaying organic matter, specifically dead organisms. Organisms that exhibit this feeding habit derive their nutrients from decomposing materials.

2. **Identifying the Organisms**:
- The question provides a list of organisms from the phylum Arthropoda. These include:
- Cockroach
- Ant
- Spider
- Scorpion

3. **Analyzing Each Organism's Feeding Habits**:
- **Cockroach**: Known to feed on decaying organic matter, including dead animals and food waste. This aligns with the saprozoic feeding habit.
- **Ant**: While some ants can be scavengers, they do not primarily feed on dead organisms in the same way cockroaches do.
- **Spider**: Predatory in nature, spiders typically capture and consume live prey, not dead organisms.
- **Scorpion**: Similar to spiders, scorpions are also predators that hunt live prey.

4. **Conclusion**:
- Based on the analysis, the organism that exhibits a saprozoic feeding habit is the **cockroach**. Therefore, the correct answer to the question is **cockroach**.
