Position of herbivores in the pyramid of biomass is

Options

A. first
B. second
C. third
D. last

Answer

### Step-by-Step Solution:

1. **Understanding the Pyramid of Biomass**:
- The pyramid of biomass is a graphical representation that shows the biomass (the total mass of living matter) at each trophic level in an ecosystem.

2. **Identifying the Levels**:
- The pyramid typically consists of four levels:
- **First Level**: Primary Producers (e.g., plants)
- **Second Level**: Primary Consumers (e.g., herbivores)
- **Third Level**: Secondary Consumers (e.g., carnivores that eat herbivores)
- **Fourth Level**: Tertiary Consumers (e.g., top predators)

3. **Position of Herbivores**:
- Herbivores are organisms that primarily consume plants (the primary producers). Therefore, they are classified as primary consumers.

4. **Locating Herbivores in the Pyramid**:
- Since herbivores are primary consumers, their position in the pyramid of biomass is at the **second level**.

5. **Conclusion**:
- The position of herbivores in the pyramid of biomass is the **second level**.

### Final Answer:
- The position of herbivores in the pyramid of biomass is **second level**.
