How do ranges of tolerance affect the distribution of organisms?
1b) How do ranges of tolerance affect the distribution of organisms? Organisms avoid the area between their optimum zone and the intolerant zone but a few organisms may wander into the zone of physiological stress. The most organisms are towards the middle of the optimum zone.
What is the ability of an organism to withstand changes in abiotic and biotic factors in an ecosystem?
Tolerance – The ability of an organism to withstand fluctuations in biotic and abiotic environmental factors.
What does a tolerance curve indicate about an organism?
A tolerance curve indicates how an organism can survive and function in conditions outside the organism’s optimal range, however its performance is reduced greatly. How does an organism’s niche differ from its habitat.
What is the relationship between an organism’s tolerance range and the habitat it occupies?

What is an organism range of tolerance?
Printer-friendly version PDF version. The range of conditions within which an organism is potentially able to survive. For example, all organisms have a maximum and minimum level of temperature, atmospheric pressure, oxygen concentration etc. within which they can survive.
What is range of tolerance in environmental science?
Range of tolerance in biology refers to the environmental conditions that are tolerable for survival.
What is the relationship between organisms and their environments?
Ecology is the study of the interaction of organisms in an area with the surrounding environment. This interaction constitutes an overall adaptation of the organisms to their environment which also includes the continuity of species.
How does range of tolerance affect an ecosystem?
Just as species have geographic ranges, they also have tolerance ranges for the abiotic environmental conditions. In other words, they can tolerate (or survive within) a certain range of a particular factor, but cannot survive if there is too much or too little of the factor.
How does tolerance affect an organism’s niche?
An organism near the tolerance limits for one factor will probably be under stress, so its ability to tolerate other factors will be reduced. The tolerance ranges for environmental factors partly define the organism’s niche. If salinity tolerance is graphed against temperature tolerance, a niche area is defined.
