Identify the incorrect statement.

Options

A. Allen`s rule says that mammals from colder climates generally have shorter ears and limbs
B. Kangaroo rat meets its water requirement by internal fat oxidation
C. Desert Iizards show physiological and behavioural adaptations to cope up with extreme tempareture
D. Xerophytes have thick cuticle and sunken stomata to minimise water loss through transpiration

Answer

To identify the incorrect statement from the options provided, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** "Allen's rule says that mammals from the colder climates generally have shorter ears and limbs."
- **Evaluation:** This statement is correct. Allen's rule indeed states that mammals in colder climates tend to have shorter appendages (ears and limbs) to minimize heat loss.

2. **Analyze the Second Statement:**
- **Statement:** "Kangaroo rat meets its water requirement by internal fat oxidation."
- **Evaluation:** This statement is also correct. Kangaroo rats can metabolize fat to produce water internally, which helps them survive in arid environments.

3. **Analyze the Third Statement:**
- **Statement:** "Desert creatures show physiological and behavioral adaptations to cope with extreme temperatures."
- **Evaluation:** This statement is incorrect. While desert creatures do exhibit behavioral adaptations, the mention of physiological adaptations is misleading in this context. The focus should be on behavioral adaptations, as physiological changes are not as prominent in some desert species.

4. **Analyze the Fourth Statement:**
- **Statement:** "Xerophytes have thick cuticle and sunken stigmata to minimize water loss through transpiration."
- **Evaluation:** This statement is correct. Xerophytes are adapted to conserve water, and their thick cuticles and sunken stomata help reduce water loss through transpiration.

### Conclusion:
The incorrect statement is the third one: "Desert creatures show physiological and behavioral adaptations to cope with extreme temperatures."
