10/19 Population Growth and Resource Availability AP

Alaska contains over 127 million acres of untouched forest land. It is the largest state in the United States,
yet with a population of nearly 700,000 people, it has the same total population as Austin, Texas. New
Jersey is one of the smallest states and home to a population of nearly 9 million, but almost 1.8 million of
its 4.4 million total land acres are untouched natural woodland. What are the reasons for the ways populations
organize themselves, and what effect does this organization have on the environment?

Why would organisms have this arrangement?

Fill in the table below by counting the number of individuals in each habitat and
then calculate the area available per individual.

1

Which habitat shows a high population density?

1

Which habitat shows a low population density?

1

Compare and contrast the terms population density and population distribution.

1

Assuming the population size stays constant, propose at two factors that might cause a
population to shift from a low density habitat to a high density habitat?

1

Animals such as lions or wolves often show clumped distribution. Give a reason why this would
be advantageous for these animals. (more than 1)

1

Which factors are dependent on the population density?

1

Describe how the food supply would be affected by the population density.

1

Describe how the levels or spread of disease would be affected by population density.

What do all the density-independent factors have in common?

Density-dependent factors are

Density-independent factors are

Density-independent factors and density-dependent factors may be interrelated. For example, a
lack of rainfall that causes a drought will impact the food supply in a habitat. Propose another
pairing of a density-independent factor and density-dependent factor that might occur.
