For example, their presence in the large intestine can help prevent the growth of potentially harmful microbes. The ability of bacteria to degrade a variety of organic c...

Carbon fixation

Carbon fixation is a process found in photosynthesis in autotrophic plants . It is when the three carbon dioxide molecules taken in each time there is a turn in the Calvin cycle in the dark reactions of photosynthesis. These three carbon dioxide molecules ...

Crassulacean acid metabolism

Crassulacean acid metabolism ( CAM ) is a carbon fixation pathway in some photosynthetic plants . CAM is usually found in plants living under arid conditions, including those found in the desert (for example, cactus). It is named after the plant family it was first discovered in, the crassulaceae . ...
