Biogeochemical cycles are the pathways through which nutrients and elements move through ecosystems, interacting with living organisms, the atmosphere, and the earth's surface. These cycles involve the processes of uptake, storage, release, and transformation of elements such as carbon, nitrogen, phosphorus, and sulfur. The study of biogeochemical cycles helps to understand how human activities, such as agriculture and industry, impact these natural processes and can lead to changes in ecosystem functioning and environmental quality. Research in this area aims to improve our understanding of these cycles and their role in the overall functioning of ecosystems, as well as to develop strategies for sustainable management of natural resources.
