FIGURE 1.

Diagram of photosynthesis model to calculate net carbon assimilation (A, μmol m⁻² s⁻¹, grey rectangle). Inputs (diamonds), parameters (triangles), functions (ellipses) and target state variable (rectangle) are shown, as is the breakdown on the model into the four processes (colours; limiting‐rate selection, carboxylation, electron transport and triose phosphate use). Arrows represent the flow of information from distal parts of the model (inputs and parameters), through intermediate functions to the end goal. Concept modified slightly from Coon et al. (2016)
