The body temperature of frog does not remain constant as it varies with the temperature of the surrounding, so frog will be called as

Options

A. Homeothermal
B. Poikilothermal
C. Warm blooded
D. Endothermal

Answer

To determine the classification of frogs based on their body temperature regulation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Body Temperature Regulation**:
- Recognize that organisms can be classified based on how they regulate their body temperature.

2. **Define Homeotherms**:
- Homeotherms are organisms that maintain a constant body temperature regardless of the external environment. Examples include mammals and birds.

3. **Define Poikilotherms**:
- Poikilotherms are organisms whose body temperature varies with the temperature of their surroundings. Their internal temperature changes according to the external environment.

4. **Identify Frog's Classification**:
- Since the body temperature of frogs changes with the surrounding temperature, they fall under the category of poikilotherms.

5. **Differentiate Between Terms**:
- Understand that warm-blooded animals are synonymous with homeotherms, while cold-blooded animals refer to poikilotherms. Frogs, being poikilotherms, are considered cold-blooded.

6. **Conclusion**:
- Based on the above definitions and classifications, we conclude that frogs are classified as poikilotherms.

### Final Answer:
Frogs will be called **poikilotherms** because their body temperature varies with the temperature of their surroundings.
