What is some evidence of the natural cycle?

Evidence of natural cycles can be observed in various phenomena, such as the changing seasons, the water cycle, and the carbon cycle. For instance, seasonal changes in temperature and daylight hours drive plant growth, animal migrations, and reproductive behaviors. Additionally, the water cycle demonstrates the continuous movement of water through evaporation, condensation, and precipitation, while the carbon cycle highlights how carbon is exchanged between the atmosphere, oceans, and living organisms. These cycles illustrate the interconnectedness of Earth's systems and their reliance on natural processes.
