Question

What characterisitc best describes the organisms listed below?

Cat, toad, wall lizard, man, red algae

• A. Eukaryotic organisms
• B. Stenothermal
• C. Eurythermal
• D. None of these

Answer 1

The correct option is C

Eurythermal

Organisms that can tolerate a wide range of temperatures are called eurythermal organisms.
A stenotherm on the other hand is a species or living organism only capable of living or surviving within a narrow temperature range. Thermophilic organisms are extremophiles (preferring extreme conditions), that thrives at relatively very high temperatures.
The organisms listed here can tolerate a wide range of temperatures and are therefore eurythermal organisms.
