Animals living in warm tropics are

Options

A. Eurythermal
B. Stenothermal
C. Megathermal
D. Both B and C.

Answer

**Step-by-Step Solution:**

1. **Understanding Warm Tropics**:
- Warm tropics refer to regions that maintain a warm climate throughout the year, typically with average temperatures ranging from 25 to 28 degrees Celsius. These regions receive significant sunlight, contributing to their warm temperatures.

2. **Identifying Animal Types**:
- The question asks about the types of animals that inhabit these warm tropical regions. The options provided are:
- A) Urethermal
- B) Stenothermal
- C) Megathermal
- D) Both B and C

3. **Defining Each Term**:
- **Urethermal**: Refers to organisms that can tolerate a wide range of temperatures, not limited to warm conditions.
- **Stenothermal**: Refers to organisms that can only survive within a narrow temperature range, which is suitable for warm tropical climates.
- **Megathermal**: Refers to organisms that thrive in high-temperature environments, typically found in tropical regions.

4. **Analyzing the Options**:
- **Option A (Urethermal)**: Incorrect, as these organisms can tolerate a wide range of temperatures and are not specifically adapted to warm tropics.
- **Option B (Stenothermal)**: Correct, as these organisms are adapted to survive in the narrow temperature range of 25 to 28 degrees Celsius.
- **Option C (Megathermal)**: Correct, as these organisms thrive in high-temperature environments typical of tropical regions.
- **Option D (Both B and C)**: This option is correct since both stenothermal and megathermal organisms are suited for warm tropical climates.

5. **Conclusion**:
- The correct answer to the question "Animals living in warm tropics are" is **D) Both B and C (Stenothermal and Megathermal)**.
