Food chain in which microorganisms breakdown the food formed by primary producers is

Options

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

Explanation

**Step-by-Step Solution:**

1. **Understanding Food Chains**: A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. It consists of producers, consumers, and decomposers.

2. **Identifying the Types of Food Chains**: There are various types of food chains, including:
- Parasitic food chain
- Detritus food chain
- Consumer food chain
- Predator food chain

3. **Focusing on the Role of Microorganisms**: The question specifically asks about a food chain where microorganisms break down food formed by primary producers.

4. **Defining Detritus Food Chain**: The detritus food chain is characterized by the breakdown of dead organic matter, known as detritus. This includes leaves, plant parts, and dead animals.

5. **Role of Microorganisms in Detritus Food Chain**: In the detritus food chain, microorganisms such as bacteria, fungi, and protozoans play a crucial role. They act as decomposers (also known as saprophytes) that break down the organic matter produced by primary producers.

6. **Conclusion**: Given that microorganisms break down the food formed by primary producers in the detritus food chain, the correct answer to the question is the **detritus food chain**.
