Which of the following is affected by temperature changes in the environment?

Options

A. Struthio
B. Balaenoptera
C. Camelus
D. Ichthyophis

Answer

To determine which of the following organisms is affected by temperature changes in the environment, we need to understand the difference between cold-blooded and warm-blooded animals.

### Step-by-Step Solution:

1. **Identify the Types of Animals**:
- There are two main categories of animals based on their body temperature regulation:
- **Warm-blooded animals (Homeotherms)**: These animals maintain a constant body temperature regardless of the environment. Examples include mammals and birds.
- **Cold-blooded animals (Poikilotherms)**: These animals have body temperatures that fluctuate with the surrounding environment. Examples include reptiles, amphibians, and most fish.

2. **Analyze the Given Organisms**:
- The question provides several organisms to consider. We need to identify whether they are warm-blooded or cold-blooded:
- **Struthio (Ostrich)**: This is a bird, and birds are generally warm-blooded. Therefore, it is not affected by temperature changes in the environment.
- **Balenoctera (Blue Whale)**: This is a mammal, and like all mammals, it is warm-blooded. Thus, it is also not affected by temperature changes.
- **Camelus (Camel)**: This is another mammal and is warm-blooded, so it is not affected by temperature changes either.
- **Amphibians**: Amphibians are generally cold-blooded, meaning their body temperature can change with the external environment.

3. **Conclusion**:
- Based on the analysis, the organisms that are affected by temperature changes in the environment are the cold-blooded animals, specifically the amphibians.

### Final Answer:
The organisms that are affected by temperature changes in the environment are cold-blooded animals, particularly amphibians.
