Chapter 22, Problem 2RQ

Summary Introduction

To review:

The nature of the carbon cycle in oxygenated and anoxic environments.

Introduction:

The carbon cycle is dependent upon the cycles of oxygen, hydrogen, and the elements to which it is bonded. The carbon cycles lie between the interconversions of carbon dioxide and other reduced forms of carbon including biomass. There is a great difference in the working of a carbon cycle depending upon the absence or presence of oxygen molecules.
