Jim Sheridan, age 12s of Ottawa, Onto, for his question:

What is the balance of nature?

In a curtain region of Grand Canyon men came along and killed all the mountain lions. Pretty soon there was a plague of rodents and other small animals who ate up all the plant life,. In this case man the hunter upset the balance of nature. For those mountain lions fed. on the furry mammals rind kept their population down. There was enough plant food to food them all.

Mother Nature provides food for a vast variety of animals. But if one variety becomes too plentiful the balance is upset. Frogs food on insects, snakes feed on frogs and skunks feed on snakes. If we kill all the snakes we get a plague of frogs, for the balance of nature will be upset,
