Population Growth Quiz

What kind of growth does the rabbit population in Australia exhibit? Why does that present a problem?

• Exponential growth; it leads to overpopulation and ecological imbalance.

• Linear growth; it is easily manageable.

• Declining growth; it poses no threat.

• Stable growth; it maintains ecological balance.

Which of the following factors affect population growth?

• Birth rate

• Death rate

• Immigration

• All of the above

On your travels through eastern Canada and the United States, you notice gray squirrels everywhere. What can you infer about the squirrels’ geographic range?

• Gray squirrels have a limited geographic range.

• Gray squirrels are native only to eastern Canada.

• Gray squirrels have a wide geographic range.

• Gray squirrels are found only in urban areas.

Populations grow exponentially when:

• Resources are unlimited and environmental conditions are ideal.

• There is a high level of predation.

• The birth rate is lower than the death rate.

• There is a significant increase in disease.

Exponential growth shows a characteristic J-shaped curve because:

• It represents a constant rate of growth over time.

• It indicates a rapid increase followed by a plateau.

• It shows a slow start followed by a rapid increase.

• It demonstrates a decrease in growth rate over time.

Logistic growth occurs when:

• The population grows exponentially without any limits.

• The growth rate decreases as the population reaches carrying capacity.

• Resources are unlimited and the environment is constant.

• The population size remains constant over time.

What factors might cause the carrying capacity of a population to change?

• Availability of resources

• Predation pressure

• Climate changes

• All of the above

Suppose that a pair of rabbits produces six offspring: three males and three females. Assume that no offspring die. Calculate if each pair of rabbits breeds only once, how many offspring would be produced each year for five generations?

• 18

• 36

• 90

• 150

At which day does carrying capacity starts?

• 35

• 1

• 25

• 15

Which of the following factors determine carrying capacity?

• Availability of resources

• Predation pressure

• Climate conditions

• All of the above
