Section 2 of "Cycles in Nature" typically covers key ecological processes such as the water cycle, carbon cycle, nitrogen cycle, and phosphorus cycle. Each cycle illustrates how essential elements and compounds move through different environmental systems, highlighting their importance for sustaining life. For example, the water cycle describes the continuous movement of water through evaporation, condensation, and precipitation. Similarly, the carbon cycle details how carbon is exchanged between the atmosphere, living organisms, and the Earth, playing a crucial role in climate regulation and energy transfer.
