Food availability modulates, and may be more influential than, other driver responses by affecting the energetic and nutritional status of animals . Laboratory studies conducted under an excess of food risk underestimating the ecological effects of climate-induced drivers, because increased feeding rates may help mitigate adverse effects . Lowered food availability from reduced open-ocean primary production  will act as an additional driver, amplifying the detrimental effects of other drivers. However, warming and higher CO2 availability may increase primary productivity in some coastal areas , ameliorating the adverse direct effects on animals . Due to the few studies addressing food availability under multiple-driver scenarios , there is medium confidence in its modulating effect on climate-induced driver responses.
