Biogeochemical Cycle Diagram: Reservoirs and Transfers
A biogeochemical cycle diagram connects atmosphere, water, soil, organisms and decomposers while distinguishing reservoirs from transfer processes.
How to keep arrows scientifically honest
A biogeochemical cycle diagram needs a named substance. Carbon, nitrogen, phosphorus and water move through different reservoirs and processes, so a generic loop should be treated as a visual framework rather than a complete scientific account.
Put reservoirs in distinct regions and label the arrows with processes such as uptake, feeding, respiration, decomposition or weathering. The biogeochemical cycle diagram generator can create an editable qualitative draft; it does not infer quantities or rates from a data table.
A focused review workflow
Check what moves, where it moves and whether the arrow describes storage or transformation. Arrow thickness and area should not imply a measured mass balance unless you supply a defined dataset and scale.

A practical prompt
Create a qualitative biogeochemical cycle diagram with atmosphere, water, soil, producers, consumers and decomposers. Label each transfer arrow and state that it is not a measured mass balance.
Common questions
What is a biogeochemical cycle?
It is the movement of matter through living systems, the atmosphere, water and geological reservoirs.
Can the diagram show real amounts?
Only when the system boundary, units, time period and input data are explicitly defined.
