A zookeeper is concerned because a population of organisms has decreased over
the past year. She does not know the cause of this decrease. She divided the
population between two new areas, but the populations continued to decrease.
Next, she altered the temperature of one habitat and found that this population
stabilized in number. This demonstrates
O exponential population growth.
O logistical population growth.
O a density-dependent factor.
O a density-independent factor.
