Nature's cycles refer to the natural processes that occur in the environment, such as the water cycle, carbon cycle, and nitrogen cycle. These cycles are essential for maintaining life on Earth. For example, the water cycle involves the continuous movement of water through evaporation, condensation, and precipitation, ensuring that ecosystems receive the moisture they need. Another important cycle is the carbon cycle, which describes how carbon is exchanged between the atmosphere, land, and oceans. Plants absorb carbon dioxide during photosynthesis, while animals release it through respiration. These cycles work together to support life and regulate the planet's climate.
