How do ranges of tolerance affect the distribution of organisms?

Answer : 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.
The second prediction is that the greater the tolerance range of a species for a particular environmental factor, the wider the distribution of that species.
Conditions that are most favorable for an organism to survive, grow and reproduce. This optimum is somewhere WITHIN the RANGE OF TOLERANCE for that organism. If an animal has a range of tolerance for temperature of 0-85 degree F somewhere within that temperature range will be the temperature that the animal grows BEST.
The biodiversity and distribution of organisms within an ecosystem is due to both abiotic (non-living) and biotic (living) factors.
Abiotic factors
- light intensity.
- temperature.
- soil pH.
- soil moisture.
