Major Abiotic Factors Temperature :

A few organisms can tolerate and thrive in a wide range of temperatures. They are called eurythermal.
But, a vast majority of them are restricted to a narrow range of temperatures. Such organisms are called stenothermal.
The levels of thermal tolerance of different species determine to a large extent their geographical distribution. Water
The salt concentration (measured as salinity in parts per thousand), is less than 5 percent in inland waters, 30-35 percent the sea and > 100 percent in some hypersaline lagoons.
Some organisms are tolerant of a wide range of salinities. They are called euryhaline.
Other organisms are restricted to a narrow range of salinities, called stenohaline.
Many freshwater animals cannot live for long in seawater and vice versa because of the osmotic problems, they would face.
