elämänkiertomalleista, or life cycle models, are conceptual frameworks used to describe the stages a living organism or a biological population undergoes from its inception to its eventual demise or the continuation of its lineage. These models help us understand the complex processes of growth, reproduction, and aging. In the context of individual organisms, life cycle models often detail developmental stages such as embryonic development, juvenile growth, maturation, reproduction, and senescence. The specific stages and their duration can vary significantly between species, reflecting adaptations to different environments and evolutionary histories. For example, the life cycle of an insect with metamorphosis is very different from that of a mammal.

At a population level, life cycle models focus on the collective dynamics of individuals. These models might describe birth rates, death rates, age structure, and migration patterns. They are crucial tools in ecology and conservation biology for predicting population trends, assessing the impact of environmental changes, and developing strategies for managing wildlife or endangered species. Factors such as resource availability, predation, disease, and climate can influence the progression through life cycle stages and affect overall population viability. Understanding these models allows for better predictions and interventions in biological systems.
