In 1893, a large area of a national forest was home to mountain lions, coyotes, and bobcats as well as about 3,000 deer. The deer ate grass, and the mountain lions, coyotes, and bobcats ate deer.
Around 1900, hunters began killing large numbers of mountain lions, coyotes, and bobcats. By 1923, there were 100,000 deer in

Using only the relationships between the plants and animals described above, which of the following statements could explain
why the population of deer increased so much?
The number of deer increased because without predators, the deer lived longer and had more offspring that also
lived longer.
The number of deer increased because populations are always increasing.
The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food to
eat.
There is not enough information to tell why the deer population increased.
