Carbon Fixation in Plants

Outside of science fiction, plants don't generally eat people. That's Biology 101 for you right there. So if they don't eat, how do plants produce energy? Well, like most autotrophs, or living things that create their own energy, plants rely on a form of carbon fixation; basically this is the process of converting, referred to as 'fixing,' inorganic carbon into organic compounds. In plants, carbon fixation is the first step of a larger three-step process called the Calvin Cycle, which adds carbon dioxide to the carbohydrate glucose in order to make energy. But really, is any of this new information? I mean, we all know that in order to make energy, plants need sunlight, carbon dioxide and water. Wait, where is the water when you are in the desert? This is a rather harsh environment, but there are still plants. How is this possible? Well, for something without a brain, plants are actually pretty clever, and when things get tough, they find alternative methods of carbon fixation to get things going.
