Natural resources are classified as renewable and nonrenewable. What is the difference between the two? whether or not the resource exists in nature
whether or not the resource can be replaced
whether or not the resource dwindles in supply
whether or not the resource is useful to humans

The difference between a renewable and a non-renewable natural resource is whether or not the resource can be replaced.

Explanation:

Natural resources are those useful for human beings and for that reason are consumed by them.

Renewable natural resources —such as water, plants and trees or solar energy— are usually renewed at a rate greater than or equal to their consumption, so they are not depleted.

A non-renewable natural resource, such as petroleum, usually has a limited existence, or its renewal speed is very slow, so its consumption can decrease its quantity or deplete it.

The difference between renewable and non-renewable resources is in their long-term availability or depletion.

Other options are not correct because:

Both types of resources exist in nature. Both resources can decrease, but one is renewable and the other can be depleted. Both renewable and non-renewable resources are useful for humans.

Well i had the same answer, so the correct answer would be a. but in this case it would be the one with plasma membrane and cell wall circled that is next to the hairy pill type of thing.
