Marine Food Web Under Threat

Phytoplanktons and zooplanktons are important parts of the marine food web. But rising ocean temperature is likely to reduce these food sources by 6 per cent and 11 per cent respectively by the end of the century. Rising water temperature may affect nutrient availability for these organisms. The impact would be more in tropical oceans, which cover 47 per cent of the global ocean surface.
