【题目】Answer the questions(根据短文内容回答下列问题)

Not many years ago, some farmers were worried because hawks were taking many of their chickens. The farmers did not know what to do. Finally, they went to the officials and asked for help.

"Kill the hawks."the officials said we'll even pay you for them. So the farms began to think of ways to kill hawks.

The farmers killed many hawks. They no longer had to worry about their chickens. But now had a new worry. Field mice were eating up a lot of the farmers' grain.

Hawks eat not only chickens but also field mice. They eat more field mice than chickens.But the farmers did not know this. When they killed a lot of hawks, they changed the balance of nature.

When people move into a new place, they often destroy many wild plants, Omen these plants are food for the animals. If the animals cannot find enough plants to eat, they will starve(饿死) and have to leave the place.

In one part of the United States, for example, the deer there like to eat a certain kind rose. The mountain lions there eat the deer. The number of deer, mountain lions and wild roses not change much if people leave things as they are.

But people killed many mountain lions in order to protect the deer. Soon there were so many deer that they ate up all the wild roses. Then the deer began to eat the green leaves of young trees. These trees were important to the farmers, So the farmers thought of ways to protect their trees. Now the deer had nothing to eat, and many of them died. This was another lesson from nature.
