Introduction:
In an ecosystem, the effects of abiotic factors are very important for the survival of species. Tolerance factor is the measurement of the range in which a particular organism can easily survive.
Answer to Problem 5A
Correct Answer:
Option (b) B.
Explanation of Solution
Explanation/justification for the correct answer:
Option (b) B. The zone of intolerance is the zone, where no individual of the organism can survive. In the graph, the zone B has 0 survival, which means this range is not suitable for organism and hence, it is the zone of intolerance.
Explanation for incorrect answer:
Option (a) A. A represent the upper limit number of individuals of a population. Hence, it is an incorrect answer.
Option (c) C. Zone C represents the zone, where some organism can survive. This is the condition, in which some individuals that can manage the physiological stress may survive.
Option (d) D. Zone D has the maximum survival rate, which means this is the range in which the factor being tested is suitable for the growth and the reproduction of the organism, that is tolerable zone. Hence, it is an incorrect answer.
