Answer 2

4) Birds is not a stenothermal organisms. Organisms that are restricted to a narrow range of temperature, are called stenothermal.

Explanation:

• Stenothermal animals which are capable of living only a certain temperature or within a very narrow range of temperature.
• The temperature to which stenothermal animals are adapted differ from one species to the other.
• The birds are the type of organisms which are able to tolerate big fluctuations in temperature as well they can tolerate a wide range of temperature such organism are said to be eurythermal hence birds are not stenothermal organisms.
• A marine or soil-dwelling animal that is capable of living only at a certain temperature or within a very narrow range of temperature.
