With regard to ecological food chain, man is a-

Options

A. Consumer
B. Producers
C. Both consumer and producer
D. Decomposer

Answer

**Step-by-Step Solution:**

1. **Understanding the Food Chain**: The ecological food chain is a sequence of organisms where each is dependent on the next as a source of food. This chain illustrates the flow of energy and nutrients from one organism to another.

2. **Identifying Trophic Levels**: In a food chain, there are different trophic levels:
- **Producers**: These are typically green plants that can synthesize their own food through photosynthesis.
- **Primary Consumers**: These are herbivores that feed on producers (plants).
- **Secondary Consumers**: These are carnivores that feed on primary consumers.

3. **Role of Man in the Food Chain**: Humans (man) do not have the ability to produce their own food. Instead, they rely on consuming plants (producers) and animals (consumers). Therefore, humans fit into the category of consumers.

4. **Eliminating Other Options**:
- **Producers**: Incorrect, as humans cannot synthesize their own food.
- **Both Consumer and Producer**: Incorrect, as humans do not produce food.
- **Decomposers**: Incorrect, as decomposers (like bacteria and fungi) feed on dead and decaying organic matter, which is not the role of humans.

5. **Conclusion**: Based on the above analysis, the correct answer to the question is that man is a **consumer** in the ecological food chain.

**Final Answer**: Man is a consumer in an ecological food chain.
