Desiccation is the process of removing moisture from a substance, often to preserve it. This technique is commonly used in food preservation, where items like fruits and vegetables are dried to prevent spoilage. By eliminating water, desiccation helps inhibit the growth of bacteria and mold, extending the shelf life of these products. In nature, desiccation can also occur in environments where water is scarce, such as deserts. Plants and animals in these areas have adapted to survive with minimal moisture. For example, the cactus stores water in its tissues, allowing it to thrive despite the harsh, dry conditions.
