The food chain ends with

Options

A. Parasites
B. Predators
C. Herbivores
D. Climax carnivores

Answer

### Step-by-Step Solution:

1. **Understanding the Food Chain**:
- A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. It typically starts with producers and moves through various levels of consumers.

2. **Identifying the Components**:
- The food chain begins with **producers** (usually plants) that convert sunlight into energy through photosynthesis.
- Next, we have **herbivores** (primary consumers) that eat the plants.
- Following herbivores, there are **carnivores** (secondary consumers) that eat the herbivores.
- Finally, we have **top carnivores** or **climax carnivores** that are at the top of the food chain.

3. **Evaluating the Options**:
- **Parasites**: They can start a food chain but are not at the end of a typical food chain.
- **Predators**: They are part of the food chain but do not end it; they are usually in the middle.
- **Herbivores**: They are primary consumers and are not at the end of the food chain.
- **Climax Carnivores**: These are the top predators in the food chain and are considered to be at the end of the food chain.

4. **Conclusion**:
- The food chain ends with **climax carnivores**, which are the top-level consumers that have no natural predators.

### Final Answer:
The food chain ends with **climax carnivores**.
