In a food chain, the third trophic level is always occupied by

Options

A. carnivores
B. herbivores
C. decomposers
D. producers

Explanation

**Step-by-Step Solution:**

1. **Understanding Trophic Levels**: In a food chain, organisms are arranged in a hierarchical order known as trophic levels. Each level represents a different stage in the flow of energy through an ecosystem.

2. **Identifying the First Trophic Level**: The first trophic level consists of producers, which are typically green plants that produce their own food through photosynthesis. For example, grass is a common producer.

3. **Identifying the Second Trophic Level**: The second trophic level is made up of herbivores, which are animals that consume the producers. These animals obtain their energy by eating plants. For instance, deer are herbivores that eat grass.

4. **Identifying the Third Trophic Level**: The third trophic level consists of carnivores, which are animals that eat herbivores. These carnivores obtain their energy by consuming the herbivores. An example of a carnivore is a lion, which preys on deer.

5. **Conclusion**: Therefore, in a food chain, the third trophic level is always occupied by carnivores, as they feed on the herbivores of the second trophic level.

**Final Answer**: The third trophic level is always occupied by **carnivores**.
