Primary consumers are :

Options

A. Carnivores
B. Herbivores
C. Decomposers
D. Omnivores

Answer

**Step-by-Step Solution:**

1. **Understanding Trophic Levels**:
- Trophic levels refer to the position an organism occupies in a food chain. Each level represents a different stage in the flow of energy through an ecosystem.

2. **Identifying Producers**:
- The first trophic level consists of producers, which are typically plants that create their own food through photosynthesis.

3. **Defining Primary Consumers**:
- The second trophic level is made up of primary consumers. These are organisms that directly consume producers (plants).

4. **Examples of Primary Consumers**:
- Primary consumers are primarily herbivores. Examples include animals like cows, goats, and rabbits that feed on plants.

5. **Clarifying Other Consumer Types**:
- It's important to differentiate primary consumers from other types of consumers:
- **Carnivores**: These are secondary and tertiary consumers that eat other animals.
- **Decomposers**: Organisms like bacteria and fungi that break down dead organic matter.
- **Omnivores**: Animals that eat both plants and animals.

6. **Conclusion**:
- Therefore, primary consumers are specifically herbivores that feed on producers.

**Final Answer**: Primary consumers are herbivores.
