Kangaroo rat is an inhabitant of :

Options

A. North American forests
B. North American deserts
C. East American grasslands
D. East American deserts

Answer

To determine the habitat of the kangaroo rat, we can follow these steps:

### Step 1: Understand the Options
The question provides four options regarding the habitat of the kangaroo rat:
- A) North American forest
- B) North American deserts
- C) East American grasslands
- D) East American deserts

### Step 2: Analyze the Habitat Needs
Kangaroo rats are known for their adaptations to arid environments. They have specific adaptations that allow them to survive in areas where water is scarce.

### Step 3: Identify Key Adaptations
Kangaroo rats have several adaptations that help them thrive in desert conditions:
- They can perform internal hydroxidation, which allows them to generate water as a by-product of metabolism.
- They have the ability to concentrate their urine significantly, minimizing water loss.

### Step 4: Eliminate Incorrect Options
- **North American forest**: This habitat is typically moist and would not support the adaptations of a kangaroo rat.
- **East American grasslands**: While these areas can be dry, they do not match the specific adaptations of the kangaroo rat.
- **East American deserts**: Similar to North American deserts, but the kangaroo rat is specifically adapted to the conditions found in North American deserts.

### Step 5: Conclusion
Based on the adaptations and habitat requirements of the kangaroo rat, the correct answer is:
**B) North American deserts**
