D. Water insects

Answer

To solve the question regarding which organisms belong to the category of primary consumers, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Primary Consumers**:
- Primary consumers are organisms that eat producers (autotrophs), which are typically plants. They are primarily herbivores.

2. **Identifying Autotrophs**:
- Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis. In most ecosystems, these are plants.

3. **Recognizing the Role of Primary Consumers**:
- Primary consumers feed on these autotrophs. Since they are herbivores, they consume plant material.

4. **Analyzing the Options**:
- We need to look at the provided options (A, B, C, D) and identify which ones are herbivores.
- For instance, if the options include animals like eagles or snakes, they are not primary consumers because they are carnivores (they eat other animals).
- If the options include insects or cattle, they are herbivores and thus can be classified as primary consumers.

5. **Selecting the Correct Answer**:
- After evaluating the options, we find that the only option that includes herbivores is option B. Therefore, the correct answer is B.

### Final Answer:
The correct answer is **B**.
