Conformers are also called

Options

A. endotherms
B. ectotherms
C. both 1 or 2
D. isotherms

Answer

**Step-by-Step Solution:**

1. **Understanding Conformers**: Conformers are organisms whose internal physiological state is dependent on the external environment. This means that their body temperature and other internal conditions change according to the surrounding conditions.

2. **Examples of Conformers**: Common examples of conformers include marine invertebrates such as worms, fishes, and crabs. These organisms do not have the ability to regulate their internal environment independently of external factors.

3. **Defining Ectotherms**: Ectotherms are organisms that rely on external sources to regulate their body temperature. They are often referred to as "cold-blooded" animals because their body temperature fluctuates with the temperature of their environment.

4. **Linking Conformers and Ectotherms**: Since conformers are influenced by external environmental factors, they are classified as ectotherms. This is because they cannot internally regulate their body temperature and must rely on external conditions, such as sunlight, to warm themselves.

5. **Differentiating from Endotherms**: In contrast, endotherms (or warm-blooded animals) can regulate their internal body temperature regardless of the external environment. This makes them regulators rather than conformers.

6. **Conclusion**: Based on the definitions and characteristics discussed, the correct answer to the question "Conformers are also called" is option 2: ectotherms.

**Final Answer**: Conformers are also called ectotherms.
