Summary Introduction

Introduction:

Ecology is the term which is used to study the interactions among organisms and their living and nonliving environment. Demographics are statistical characteristics that are used by ecologists to describe a population.

Answer to Problem 1SA

Correct answer:

Most commonly, individuals of a natural population show a clumped distribution through their habitat. Hence, the correct answer is option b.

Explanation of Solution

Reason for correct answer:

Option b. is given as “clumped”.

Population distribution is the term which is used to describe the location of individuals relative to one another. A patchy distribution of resources is responsible for the most common population distribution pattern to be clumped one.

Reason for incorrect answer:

Option a. is given as, “random”.

Population distribution pattern can be clumped, random or near uniform but, patchy distribution of resources favor the clumped population distribution pattern. Hence, option a. is incorrect.

Option c. is given as, “near uniform”.

Intense competition for limited resources may favor the near uniform population distribution pattern but commonly the members of a population are clumped together. Hence, option c. is incorrect.

Hence, the options a. and c. are incorrect.

Conclusion

Commonly, the members of a population show a clumped distribution pattern through their habitat. Thus, the correct option is b.
