The place of human being in food chainin an ecosystem is as a:

Options

A. producer
B. consumer
C. decomposer
D. both a and b

Answer

To determine the place of human beings in the food chain of an ecosystem, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Food Chain**:
- A food chain represents the flow of energy and nutrients in an ecosystem. It consists of producers, consumers, and decomposers.
- Producers are organisms that can make their own food (like plants through photosynthesis).
- Consumers are organisms that cannot produce their own food and rely on other organisms for energy.
- Decomposers break down dead organic material and recycle nutrients back into the ecosystem.

2. **Identifying Human Beings' Role**:
- Human beings do not produce their own food; instead, they rely on other organisms (plants and animals) for sustenance.
- This means that humans are not producers.

3. **Classifying Humans as Consumers**:
- Since humans consume food produced by other organisms, they are classified as consumers.
- Consumers can be further categorized into primary consumers (herbivores), secondary consumers (carnivores), and tertiary consumers (top predators). Humans can fit into various categories depending on their diet.

4. **Conclusion**:
- Therefore, the place of human beings in the food chain is as consumers. They play a crucial role in the ecosystem by consuming energy from other organisms and converting it into energy through respiration.

### Final Answer:
Human beings are classified as consumers in the food chain of an ecosystem.
