<p>Modelled relationships between temperature <i>T</i><sub><i>C</i></sub> and daily primary production <i>P</i><sub><i>P</i></sub> and (a) median estimated consumer biomass <i>B</i> (g m<sup>-2</sup> in <i>M</i> range 1 to 10<sup>6</sup> g), (b) median estimated consumer production <i>P</i><sub><i>C</i></sub> (g m<sup>-2</sup> in <i>M</i> range 1 to 10<sup>6</sup> g), (c) ratio of primary production (g m<sup>-2</sup> yr<sup>-1</sup>) to consumer biomass <i>B</i><sub><i>C</i></sub> (g m<sup>-2</sup> yr<sup>-1</sup> in <i>M</i> range 1 to 10<sup>6</sup> g) and (d) ratio of primary production (g m<sup>-2</sup> yr<sup>-1</sup>) to consumer production <i>P</i><sub><i>C</i></sub> (g m<sup>-2</sup> yr<sup>-1</sup> in <i>M</i> range 1 to 10<sup>6</sup> g). In all simulations <i>Z</i><sub><i>e</i></sub> was assumed to be fixed at 50 m and <i>Z</i> at 200 m. Chlorophyll concentration was estimated from primary production using a relationship established from the GCM outputs. Values of <i>T</i><sub><i>C</i></sub> and <i>P</i><sub><i>P</i></sub> that fell outside ranges including 99.99% of GCM outputs for the world’s oceans are masked. Contours indicate combinations of <i>T</i><sub><i>C</i></sub> and <i>P</i><sub><i>P</i></sub> that include 70% (black), 90%, 95% and 99% (pale grey) of GCM outputs.</p>
