Which of the following is incorrect?

Options

A. Mammals living in hot climate are large sized
B. Amphibians living in colder regions are large sized
C. Reptiles living in hot climate are small sized
D. Mammals living in warmer places are small sized

Answer

To determine which statement is incorrect regarding the size of animals in relation to their climate, we can analyze each option based on ecological principles, particularly Bergmann's rule.

### Step-by-Step Solution:

1. **Understand Bergmann's Rule**: This ecological principle states that within a species, individuals tend to be larger in colder environments and smaller in warmer environments. This is because larger animals have a smaller surface area-to-volume ratio, which helps them retain heat.

2. **Analyze Each Option**:
- **Option 1**: "Mammals living in hot climate are large sized."
- According to Bergmann's rule, this statement is incorrect. Mammals in hot climates are generally smaller to help dissipate heat.

- **Option 2**: "Amphibians living in colder regions are large sized."
- This statement aligns with Bergmann's rule, as larger body sizes in colder climates help retain heat.

- **Option 3**: "Reptiles living in hot climate are small sized."
- This statement is generally true. Reptiles, being ectothermic, often have smaller sizes in hot climates to avoid overheating.

- **Option 4**: "Mammals living in warmer places are small sized."
- This statement is also true and consistent with Bergmann's rule.

3. **Identify the Incorrect Statement**:
- From the analysis, the first option is incorrect: "Mammals living in hot climate are large sized." In reality, they are typically smaller.

### Conclusion:
The incorrect statement is: "Mammals living in hot climate are large sized."
