B. Herbivores
C. Carnivores
D. AII

Answer

### Step-by-Step Solution:

1. **Understanding the Food Chain**:
- A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another. It illustrates the feeding relationships between different organisms in an ecosystem.

2. **Identifying the Components of a Food Chain**:
- The food chain consists of various levels of organisms, primarily categorized into producers and consumers.

3. **Producers**:
- The first level of the food chain consists of **producers**, which are typically plants. They convert sunlight into energy through photosynthesis and form the base of the food chain.

4. **Consumers**:
- The second level consists of **consumers**, which can be divided into:
- **Primary Consumers (Herbivores)**: These organisms eat the producers. Examples include rabbits, deer, and insects.
- **Secondary Consumers (Carnivores)**: These organisms eat primary consumers. Examples include snakes and birds of prey.
- **Tertiary Consumers (Carnivores)**: These are higher-level carnivores that eat other carnivores.
- **Omnivores**: These organisms can eat both plants and animals, such as humans and bears.

5. **Conclusion**:
- Therefore, a food chain consists of **plants (producers)**, **herbivores (primary consumers)**, and **carnivores (secondary and tertiary consumers)**. The correct answer to the question is that a food chain consists of all these components.

### Final Answer:
The food chain consists of plants, herbivores, and carnivores, which means the correct answer is "all of them."
