Law Of Tolerance And Quadratic Models
The Law of Tolerance states that a species’ performance diminishes as an abiotic factor deviates from its optimal range. If the physiological stress on a species is modeled as a function of temperature, x, using the quadratic equation , how would an increase in the coefficient a affect the potential distribution of that species?
A
It steepens the curve, causing deviations from the optimum to become more pronounced, which may reduce the habitable range.
B
It shifts the optimum range upward without altering the steepness of the curve.
C
It has no significant effect on species distribution as a merely scales the function without affecting tolerance limits.
D
It flattens the curve, thereby increasing the range of tolerable temperatures.
