Consumers in food webs are dependent on primary producers for the synthesis of essential fatty acids and amino acids. Only a few phytoplankton taxa are able to synthetize EPA (20:5w3) and DHA (22:6w3) that physiologically most important fatty acids for consumers. Climate change has direct influences on lakes chemistry and physics which will further effect on phytoplankton community structure and availability of essential fatty acids and amino acids. Temprature, nutrients and humic rich dissolved organic matter impact on the synthesis of EPA and DHA in phytoplankton and transfer in freshwater food webs will be studied different type of lakes, which after affect to the availability of these essential biomolecules will be modelled.
