c. willow
The food source's scarcity that caused the Yellowstone National Park beaver population to decrease is c. willow.
To determine which food source's scarcity caused the decrease in the Yellowstone National Park beaver population, we need to assess the feeding habits of beavers.
Beavers primarily feed on the bark, twigs, and leaves of various tree species. In the case of the Yellowstone National Park beaver population, they heavily rely on a specific tree species for their diet: willow.
Therefore, the correct answer is c. willow. The scarcity of willow in the area resulted in a decrease in the beaver population in Yellowstone National Park.
To find out this information, you can refer to reliable sources such as research papers, scientific studies, or official reports on beaver populations in Yellowstone National Park. These sources often provide detailed information on beaver feeding habits and the impact of certain food sources' scarcity on their population dynamics.
