Human Population Growth-Bio Acc

The first event that occurs in a country that is experiencing rapid population growth and entering Stage 2 of the Demographic Transition is

• the birth rate increases (more births)

• the death rate decreases (fewer deaths)

• emigration increases (people migrate out)

• the death rate increases (more deaths)

Demographic transition is change from high birthrates and high death rates to

• exponential growth.
• low birthrates and low death rates.
• low birthrates and high death rates.
• indefinite growth.

The anticipated human population by the year 2050 is about

• 7 billion.

• 9 billion.

• 9 trillion.

• 78 billion.

In Rwanda, there are more young children than teenagers, and more teenagers than adults. This age structure indicates a population that

• has stopped growing.
• will double in 30 years.
• has a steady growth rate.
• will decrease in 30 years.

Most of the worldwide human population is growing exponentially because

• human populations have not reached their exponential curve.
• most countries have not yet completed the demographic transition.
• human populations do not conform to the logistic model.
• the food supply is limitless.

The human population in Canada contains almost equal numbers of people in each age group. This means that the population in Canada will

• double in 30 years.
• grow slowly but steadily.
• decrease exponentially.
• decrease to its carrying capacity.

What evidence do you see in the graph that the United States is gradually entering the last stage of demographic transition?

• The age structure for the US has fewer children in the younger age categories

• The age structure for the US has fewer adults in the middle age categories

• The age structure for the US has greater numbers in the 15-19 age category

• The age structure for the US shows females living longer than males.

Which of the following would most likely occur if a population exceeded the carry capacity of the environment?

• The birth rate would likely increase.
• Birth rate would be equal to the death rate.
• The death rate would increase.
• Immigration would increase.
