elinkaarimuotoihin
Elinkaarimuotoihin, also known as life stages or developmental stages, refers to the distinct phases an organism progresses through from its beginning to its end. These stages are characterized by specific biological, physiological, and behavioral changes. For most multicellular organisms, the life cycle typically begins with fertilization, leading to an embryonic or larval phase. This is followed by a juvenile or growth phase where the organism matures. Subsequently, the organism enters a reproductive phase, where it is capable of procreation. Finally, it undergoes senescence, a period of decline, ultimately leading to death.
The specific names and duration of these life stages vary greatly across different species and even within
