Options

A. Grazing food chain
B. Predator food chain
C. Parasitic food chain
D. Detritus food chain

Answer

To identify the type of food chain given in the question, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Food Chain**:
- The food chain provided is: Dead animal → Blow fly maggots → Common Frog → Snake.

2. **Understand the Role of Each Organism**:
- **Dead Animal**: This is the starting point of the food chain, representing decomposing organic matter.
- **Blow Fly Maggots**: These are detritivores that feed on dead organic matter.
- **Common Frog**: This organism preys on the maggots.
- **Snake**: This predator feeds on the frog.

3. **Determine the Type of Food Chain**:
- The food chain starts with a dead animal, which is decomposing organic matter. This indicates that the food chain is not starting with living plants or herbivores.
- In ecological terms, a food chain that begins with dead organic matter and involves detritivores is classified as a **detritus food chain**.

4. **Conclusion**:
- Based on the analysis, the food chain is identified as a **detritus food chain**.

### Final Answer:
The food chain is a **detritus food chain**.
