V. Read the passage carefully, then choose the correct answers:
The natural environment includes all natural resources that are necessary for life: the air, the oceans, the sun and the land. Because they are vital for life, these resources must be protected from pollution and conserved. Ecologists study their importance and how to use them carefully.
According to ecologists, resources are divided into two groups: renewable and non-renewable. When a resource is used, it takes some time to replace it. If the resource can be replaced quickly and easily, it is called renewable. If it cannot be replaced quickly and easily, it is called non-renewable. For example, grass for animals is a renewable resource. When cows eat the grass, the resouce is used. If the soil is fertilized and protected, more grass will grow. Coal, however, is non-renewable because it takes millions of years to make coal. All fossil fuels are nonrenewable resources.
