What is a major difference between the carbon and nitrogen cycles?
The carbon cycle involves plants, while the nitrogen cycle doesn't.
The carbon cycle involves the atmosphere, while the nitrogen cycle doesn't.
The carbon cycle involves the conversion of carbon to different molecules, while the nitrogen cycle involves the conversion of nitrogen to different molecules.
The carbon cycle primarily occurs in aquatic environments, while the nitrogen cycle occurs primarily on land.
Explanation
Both involve cycling elements, but different forms. In this case, carbon cycles through being converted to various molecules, while nitrogen also converts.
