Biogeochemical cycles involve the exchange of matter between living organisms and the environment from "summary" of NCERT Exemplar Problems-Solutions BIOLOGY class 12th by Arihant Experts
Biogeochemical cycles are essential processes that involve the movement of matter between living organisms and the environment. These cycles play a crucial role in maintaining the balance of various elements in the ecosystem. The exchange of matter occurs through the biotic and abiotic components of the ecosystem, creating a dynamic relationship between living organisms and their surroundings. The biogeochemical cycles encompass the circulation of elements such as carbon, nitrogen, phosphorus, and water. These elements are essential for the survival of living organisms and are constantly being recycled in the environment. For example, in the carbon cycle, carbon dioxide is taken in by plants during photosynthesis and released back into the atmosphere through respiration. This continuous exchange of carbon ensures that the element remains available for all organisms in the ecosystem. Similarly, the nitrogen cycle involves the transformation of nitrogen into...
