Life on Earth depends on carbon. In fact, about 18.5 percent of a human body's mass is carbon. How carbon is taking in and given off through animals' breathing, the burning of fossil fuels, and more can be shown in the model known as the carbon cycle. Though this concept can be confusing, all readers have a chance to understand this concept through the text and simple diagrams in this book. Both struggling readers and those looking for review can find the most important components and vocabulary of the carbon cycle in low-level, accessible text.
