Generate a multiple-choice question stem based on the context, options and answer.\n\nContext:\nBut in this temperate forest there are more fungi, capable of breaking down complex woody materials. Looking to harvest more food from the apple\u2019s remains, these microbes release enzymes that trigger a chemical reaction called oxidation. This breaks down the molecules of organic matter, releasing energy, carbon, and other nutrients in a process called mineralization. Then microbes consume the carbon and some nutrients, while excess molecules of nitrogen, sulfur, calcium, and more are left behind in the soil. As insects and worms eat more of the apple, they expose more surface area for these microbial enzymes to oxidize and mineralize. Even the excretions they leave behind are mined by microbes. This continues until the apple is reduced to nothing\u2014 a process that would take one to two months in a temperate forest. Environments that are hot and wet support more microbes than places that are cold and dry, allowing them to decompose things more quickly. And less complex organic materials break down faster. But given enough time, all organic matter is reduced to microscopic mineral nutrients. The atomic bonds between these molecules are too strong to break down any further. So instead, these nutrients feed plant life, which grow more food that will eventually decompose.\nOptions:\nA) mineralization\nB) immobilization\nC) nitrification\nD) carbonization\nAnswer:\nA) mineralization\nQuestion:\n
