FEW ORGANISMS CAN TOLERATE AND THRIVE IN A WIDE RANGE OF TEMPERATURES , SUCH ORGANISMS ARE KNOWN AS EURYTHERMAL. MAJORITY OF ORGANISMS ARE RESTRICTED TO ANARROW RANGE OF TEMPERATURES , SUCH ORGANISMS ARE KNOWN AS STENOTHERMAL.

As adjectives the difference between eurythermal and stenothermal. is that eurythermal is (biology. of an organism) able to tolerate a wide range of temperature while stenothermal is (biology) able to tolerate only a narrow range of temperatures.
