The sulfur cycle includes processes like evaporation, absorption by plants, and return to the environment through decomposition and weathering. Four important biogeochemical processes that cycle nutrients are the carbon cycle, nitrogen cycle, phosphorus cycle, and water cycle These processes are vital for maintaining life on earth and ensuring the availability of essential nutrients in ecosystems. Biogeochemical cycles are the vital processes that recycle essential elements like carbon, nitrogen, and phosphorus through the environment These cycles ensure that life can thrive by maintaining a balance between living organisms and their surroundings. Nutrients are acquired by green plants from the soil through their roots, passed on to herbivores and then to carnivores as organisms consume each other, and ultimately return to the soil through the decomposition of dead remains by detritivores and decomposers.
Nutrients move through the ecosystem in biogeochemical cycles A biogeochemical cycle is a circuit/pathway by which a chemical element moves through the biotic and the abiotic factors of an ecosystem It is inclusive of the biotic factors, or living organisms, rocks, air, water, and chemicals. Unfortunately, recent human activities have significantly altered the biogeochemical cycles In this chapter, we will learn about carbon, nitrogen, and phosphorus cycles. Key cycles include the water cycle, carbon cycle, nitrogen cycle, and phosphorus cycle.
Nitrogen is cycled through processes such as nitrification, decomposition and denitrification Phosphorus is cycled through processes such as weathering, erosion, and decomposition.
