Population _______________ is the number of individuals of a species per unit of habitat area or volume at a given time. (a) dispersion (b) density (c) survivorship (d) age structure (e) demographics

Expert Solution & Answer

Summary Introduction

Introduction: The study of change in population is termed as population dynamics. Population ecology can be defined as both the number of individuals for a particular species in an area and dynamics of the population. It is the study of interaction of population with the environment, such as competition of individuals for food and other resources.

Answer to Problem 1TYU

Correct answer: At a given time, the number of individuals of a species per unit of habitat area is described as population density.

Hence, the correct answer is option (b).

Explanation of Solution

Reason for the correct answer:

The population density of a particular area refers to as the number of individuals of a species per unit volume or habitat area at a particular time. Population density varies according to the time of year and type of the environment. Population density of an area can also vary according to the different season.

Option (b) is given as “density”.

The number of individuals of a species per unit habitat volume at a given time is known as population density. Hence, option (b) is correct.

Reasons for incorrect answers:

Option (a) is given as “dispersion”.

Population dispersion is described as the movement of individuals from one population to another population. It shows the migration rate of a population. Hence, option (a) is incorrect.

Option (c) is given as “survivorship”.

Survivorship gives the probability about the survival of an individual at a certain age. It does not tell about the number of individuals per unit volume. Hence, option (c) is incorrect.

Option (d) is given as “age structure”.

Age structure is the proportion of individuals at each age; therefore, it does not tell about the number of individuals per unit habitat area. Hence, option (d) is incorrect.

Option (e) is given as “demographics”.

Population demographics are statistics related to human population and does not tell about the number of individuals of a species per unit volume at a given time. Hence, option (e) is incorrect.

Hence, options (a), (c), (d), and (e) are incorrect.

Conclusion

The total number of individuals of a specific species per unit habitat area at a given time is described as the population density of that species.
