Which of the following is the correct representation of detritus food chain?

Options

A. Detritus (dead organic matter) `to` detrivores `to` decomposers
B. Detritus `to` microbes `to` detrivores `to` decomposers
C. Detrivores `to` organic matter `to` microbes `to` decomposers
D. Grass `to` detrivores `to` decomposers

Answer

To determine the correct representation of the detritus food chain, let's analyze the options provided step by step.

### Step-by-Step Solution:

1. **Understanding the Detritus Food Chain**:
- The detritus food chain begins with dead organic matter, referred to as detritus. This is the starting point of the chain.

2. **Identifying Components**:
- The primary components of a detritus food chain include:
- **Detritus**: Dead organic matter.
- **Detrivores**: Organisms that consume detritus (e.g., earthworms).
- **Decomposers**: Microorganisms (like bacteria and fungi) that break down dead organic matter.

3. **Evaluating the Options**:
- **Option 1**: Detritus, detrivores, and decomposers.
- This option starts with detritus and includes both detrivores and decomposers, which aligns with the structure of a detritus food chain.
- **Option 2**: Detritus, microbes, detrivores, and decomposers.
- This option includes microbes, but it is unclear how they fit in the sequence. It does not clearly represent the flow from detritus to detrivores to decomposers.
- **Option 3**: Detrivores, organic matter, microbes, decomposers.
- This option starts with detrivores, which is incorrect as the chain should start with detritus.
- **Option 4**: Grass, detrivores, and decomposers.
- This option incorrectly starts with grass, which is a producer and not part of the detritus food chain.

4. **Conclusion**:
- The correct representation of the detritus food chain is **Option 1**: Detritus, detrivores, and decomposers.

### Final Answer:
**Option 1: Detritus, detrivores, and decomposers** is the correct representation of the detritus food chain.
