Calcium levels in various organisms<br /><br />A person contains about 1 kg to 1.5 kg of calcium. <br />This is approximately 1.5% calcium.<br />Cattle - also 1.5% calcium, but some marine organisms may contain more calcium. <br />For example, corals that contain up to 20% calcium. <br />Other interesting organisms that contain a lot of calcium are echinoderms (similar to hedgehogs). <br />These organisms contain up to 45% calcium.<br /><br />#calcium #biochemistry #Biochemistrycalcium #Calciumconcentration #Calciumcoral #Calciuminorganisms #Calciumlevels #corals #echinoderms
