Answer 2

Water, carbon and nitrogen are transferred from one part to other of earth (both living and non living part) in different forms and reach to the starting point again.

This is a cyclic process and thus known as "cycles"

For example :

Carbon of carbon dixoide is being converted to carbohydrates by plants through photosynthesis. this is being eaten by consumers and then they digest it and release back carbon dixoide agin to atmosphere. so in this way there are other parts of carbon cycle also.
