- Eurythermal
- Stenothermal
- Euryhaline
- Stenohaline
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Organisms are named according to the range of a factor they can tolerate: 'eury' means wide and 'steno' means narrow.
Step 2: Temperature or salinity
'Thermal' refers to temperature and 'haline' refers to salt. So the terms are eurythermal and stenothermal for temperature, and euryhaline and stenohaline for salinity.
Step 3: Apply to polar bears
Polar bears tolerate only a narrow range of temperature, so they are stenothermal.
Final Answer:
Polar bears are stenothermal. \[ \boxed{\text{(B) }\text{Stenothermal}} \]
