Question

which of the following statements about tolerance range is true?
a. tolerance range is different for different organisms.
b. the tolerance range is the total number of organisms that can be supported by an ecosystem.
c. tolerance range is affected by biotic factors in an ecosystem.
d. the available water supply does not impact an organisms tolerance range.

please select the best answer from the choices provided

a
b
c
d

Explanation:

The tolerance range refers to the span of environmental conditions (such as temperature, salinity, or pH) within which a particular species can survive and function. Because different species have evolved unique physiological adaptations to their specific niches, this range varies significantly from one organism to another. Option B describes carrying capacity, option C is incorrect because tolerance ranges are primarily defined by abiotic factors, and option D is incorrect because water availability is a critical abiotic factor that directly impacts an organism's survival and tolerance limits.

Answer:

A. Tolerance range is different for different organisms.
