Problem

The graph below represents the size of a bird population over time.
A line graph with Population size on the y axis and Time on the x axis. A curve begins at the origin and increases rapidly until it nears the top of the y axis. The curve then begins to curve down slightly before increasing and then decreasing again.
The population experiences a period of heavy rainfall that causes the number of edible seeds in the birds’ habitat to increase.
Which of the following graphs represents how the size of the bird population would likely be affected over time by this environmental change?
