A researcher is studying the global biogeochemical cycling of nutrient X, and they have determined that its storage rate in the oceanic subsystem is -10 Pg y¹. There are fast and slow biogeochemical cycles. Fast cycle operate in the biosphere and slow cycles operate in rocks. Fast or biological cycles can complete within years, moving substances from atmosphere to biosphere, then back to the atmosphere. Slow or geological cycles can take millions of years to complete, moving substances through the Earth's crust between rocks, soil, oc…
WebJan 8, 2024 · The water cycle is perhaps the most well-known example of a biogeochemical cycle. Chemical elements must constantly be circulated throughout the ecosystem in order for living organisms to survive. When organisms absorb or ingest nutrients, the nutrients are then carried throughout the food chain. WebBiogeochemical cycles are described and modelled in terms of reservoirs, material, fluxes, sources, sinks, and budgets. The reservoir is the amount of material in a given Earth system, such as oxygen in the atmosphere, or water in the ocean. The flux is the amount of material moved from one reservoir to another – for example, the amount of ...
