Abstract: Biogeochemical cycles represent natural routes through which vital chemical elements circulate among the atmosphere, hydrosphere, lithosphere, and biosphere. These cycles are crucial for preserving ecological equilibrium and supporting life on our planet. Among the significant biogeochemical cycles, carbon, Sulphur, and oxygen cycles are essential in regulating environmental processes and aiding living organisms. The carbon cycle encompasses the transfer of carbon through photosynthesis, respiration, decomposition, and combustion, thus sustaining atmospheric carbon dioxide levels. The Sulphur cycle involves the transit of sulphur compounds through rocks, soil, water, atmosphere, and organisms via weathering, volcanic activities, microbial decomposition, and industrial emissions. The oxygen cycle is intricately linked to the carbon cycle, where oxygen is generated during photosynthesis and utilized in respiration, oxidation, and combustion processes. These interrelated cycles facilitate nutrient recycling, energy transfer, and the maintenance of ecosystem stability. Human activities such as deforestation, industrialization, mining, fossil fuel combustion, and environmental pollution have disrupted the natural equilibrium of these cycles, resulting in climate change, acid rain, global warming, ozone depletion, and ecological imbalance. Consequently, comprehending the operation and importance of carbon, Sulphur, and oxygen cycles is vital for environmental conservation, sustainable resource management, and safeguarding life on Earth.
