Sentences with phrase «marine organisms need»

This is significant because coral reefs and shelled marine organisms need carbonate ions to form the lime or calcium carbonate that composes their skeletons and shells.

Not exact matches

«So the contamination of long - lived radionuclides in different organisms in the local marine food webs needs to be monitored continually.»

Ocean acidification reduces carbonate ion saturation, making it harder for marine organisms to produce the CaCO3 that they need to form their shells and frameworks.

While this is an appropriate approach in view of the scarcity of biological information, there is a clear need to establish a reliable data base on tolerance levels for ocean acidification in key groups of ocean - acidification sensitive marine organisms in order to reach a more informed recommendation.

Acidification increases the corrosiveness of the water and is also driving a decline in the amount of carbonate ion, needed to make aragonite and calcite, two forms of calcium carbonate that many marine organisms use to build their shells and skeletons.
