biogeochemical cycle
Let an agent explain biogeochemical cycles and their components, describe human impacts with sourced data, and support education and environmental analysis.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain biogeochemical cycles and their components, describe human impacts with sourced data, and support education and environmental analysis.
The pathway by which a chemical element or compound moves through the biotic and abiotic compartments of Earth, such as the carbon, nitrogen, phosphorus, sulfur, water, silica and mercury cycles, driven by biological, geological and chemical processes; biogeochemical cycles sustain ecosystems and are perturbed by human activity.
What it is for: Ecology, earth science and environmental management.
It can be explain a specific cycle and its reservoirs; quantify fluxes and residence times with sources; describe human perturbations; support teaching and modelling.
Distinguishing features

What it looks like
Not physical; diagrams of reservoirs and fluxes.
How it is recognised
Reservoirs and fluxes
Biological and geological steps
A food web tracks energy and organisms, not elements
