Dies refers to the end of life for an organism, marking the cessation of biological functions that sustain life. This process can occur due to various factors, including age, disease, injury, or environmental conditions. When an organism dies, its body undergoes decomposition, returning nutrients to the ecosystem. In many cultures, death is a significant event that often leads to rituals or ceremonies to honor the deceased. Understanding the concept of death is essential in fields such as biology, medicine, and psychology, as it influences how societies cope with loss and the natural cycle of life.
