Changes, or alterations, refer to modifications made to an object, idea, or process. These adjustments can occur in various contexts, such as in nature, technology, or personal behavior. For example, when a tree loses its leaves in autumn, it undergoes a natural change that prepares it for winter. In human activities, changes can be intentional or unintentional. A company may alter its marketing strategy to better reach customers, while a student might change their study habits to improve academic performance. Overall, changes are essential for growth and adaptation in both living organisms and systems.
