The American Plains bison is a grassland species that eats mostly grasses. By the late 1800s, hunting came close to causing this animal to disappear from the western United States. In the early 1900s, landowners and the U.S. government took steps to save the bison. The graph shows data collected in northern Yellowstone National Park between 1902 and 1915.

Which of the following events could have caused the change shown in the graph? Choose the TWO that apply.

• natural disaster

• decrease in food

• increase in shelter

• departure of bison

• decrease in hunting

A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how the graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.

• The population would continue to increase. There should be plenty of resources still available to the bison.

• The population will stay the same. The best adapted bison will survive but equal amounts will die, keeping the population constant.

• The population will decrease. Drought will cause fewer resources to be available to the bison and many will die.

• Any of the following could occur.
