The cycle of life, also known as the life cycle, refers to the series of changes that a living organism undergoes from its beginning to its end. This concept applies to all forms of life, from the simplest bacteria to the most complex animals and plants. The fundamental stages typically include birth or beginning, growth and development, reproduction, and finally, death.

In most organisms, the cycle begins with reproduction, which produces a new individual. This new individual then grows and develops, maturing over time. Once mature, the organism is capable of reproduction, passing on its genetic material to the next generation. This stage is crucial for the continuation of the species. Eventually, the organism ages and its body functions decline, leading to death.

The specific stages and their duration can vary greatly between species. For example, insects often undergo metamorphosis, a dramatic transformation from larva to adult. Plants typically progress from seed to seedling, then to mature plant, flowering and producing seeds before their life cycle concludes. Even organisms that reproduce asexually, like some bacteria, have a cycle of division and growth.

The cycle of life is a fundamental principle in biology, underpinning ecological processes. The death of an organism returns nutrients to the environment, which are then utilized by new life, demonstrating a continuous, interconnected process. This perpetual renewal is essential for the balance and sustainability of ecosystems.
