Herbivores are-

Options

A. Primary consumer
B. T3
C. T2
D. Primary consumers orT2 or Consumer of 1 st order.

Answer

### Step-by-Step Solution:

1. **Understanding Herbivores**:
- Herbivores are organisms that primarily consume plants. They play a crucial role in the ecosystem as they are the first level of consumers that feed directly on producers (plants).

2. **Defining Primary Consumers**:
- Primary consumers are organisms that eat producers. In ecological terms, herbivores fall under this category because they rely on plants for their energy and nutrients.

3. **Trophic Levels**:
- In an ecosystem, organisms are categorized into different trophic levels based on their feeding relationships.
- T1 (Trophic Level 1) consists of producers (plants).
- T2 (Trophic Level 2) consists of primary consumers (herbivores).
- T3 (Trophic Level 3) consists of secondary consumers (carnivores that eat herbivores).
- T4 (Trophic Level 4) consists of tertiary consumers (carnivores that eat other carnivores).

4. **Identifying the Correct Option**:
- Since herbivores are classified as primary consumers, they belong to T2 in the trophic levels. Therefore, the correct answer to the question "Herbivores are" is "Primary Consumers" or "T2".

### Final Answer:
Herbivores are primary consumers (T2).
