b) nonrenewable resources are so inexpensive that you mean don’t rely on remover ones
c) nonrenewable resources are free so people use them up quickly
d) once nonrenewable resources are used, they cannot be replaced, so we are not able to acquire more

The correct answers are:

A) Nonrenewable resources create terrible pollution problems;

D) Once nonrenewable resources are used, they cannot be replaced, so we are not able to acquire more;

The nonrenewable resources are by far the most used resources across the globe. From side they are relatively cheap and are very efficient, but from the other side they are the biggest polluters and their reserves are becoming less and less. Being the biggest polluters, this resources create a lot of problems like the bad air quality, acid rains, and the climate change. Also, this resources are limited, so once the reserves of them are spent there will be no more of them, thus the humanity will be in big trouble if a proper solution is not found until then.

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its
