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 resource 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. 28.
