Check your understanding of concepts from 14·14–14·16 The human population is growing rapidly by answering the following questions.

1.

1. The age-structure diagram of a human population in a developing country has the shape of:

a totem pole.

a pyramid.

an hourglass.

a funnel.

a rectangle.

Correct. (See section 14·14 Age pyramids reveal much about a population.)

Incorrect. (See section 14·14 Age pyramids reveal much about a population.)

2.

2. The “demographic transition” seen in human populations ultimately results in:

no births and no deaths.

low birth rates and low death rates.

high birth rates and high death rates.

high birth rates and low death rates.

None of the above is correct.

Correct. (See section 14·15 As less-developed countries become more developed, a demographic transition often occurs.)

Incorrect. (See section 14·15 As less-developed countries become more developed, a demographic transition often occurs.)

3.

3. Which of the following is NOT a mechanism by which humans have so far avoided growth beyond their carrying capacity?

the ability to cure previously fatal diseases

the ability to live in higher densities than before

the ability to expand into new habitats

the ability to produce more food with that previously possible

All of the above are mechanisms by which humans have avoided reaching their carrying capacity.

Correct. (See section 14·16 Human population growth: how high can it go?)

Incorrect. (See section 14·16 Human population growth: how high can it go?)

4.

4. Which of the following is TRUE about estimating human carrying capacity?

The United States is a model country when it comes to sustainable living.

Some countries have more resources than their populations can currently use.

Humans are currently living in all potential habitats offered on earth.

Technological innovations usually decrease carrying capacity.

Quality of life is rarely a factor used in determining the carrying capacity.

Correct. (See section 14·16 Human population growth: how high can it go?)

Incorrect. (See section 14·16 Human population growth: how high can it go?)

5.
