Role of Nitrogen o Protein and DNA Synthesis: Nitrogen is a key component of amino acids, proteins, and nucleic acids (DNA and RNA), which are essential for the growth and reproduction of marine organisms.o Eutrophication: Excess nitrogen and phosphorus from human activities (e.g., agriculture, wastewater discharge) can lead to algal blooms, oxygen depletion, and marine ecosystem disruptions.Ecological Impact o Nutrient Limitation: In many oceanic regions, nitrogen or phosphorus availability limits primary production, affecting entire food webs.2.3.

Role of Nitrogen
• Protein and DNA Synthesis: Nitrogen is a key component of amino acids, proteins, and nucleic acids (DNA and RNA), which are essential for the growth and reproduction of marine organisms.
• Primary Production: Nitrogen is a major nutrient required by phytoplankton, the primary producers in marine food webs.
• Nitrogen Cycle: Bacteria convert nitrogen into usable forms (e.g., nitrate and ammonium), which support marine productivity.

   Role of Phosphorus
   • Energy Transfer: Phosphorus is a component of ATP (adenosine triphosphate), the molecule that stores and transfers energy in cells.
   • Membrane Structure: Phospholipids, which form cell membranes, require phosphorus.
   • DNA and RNA Synthesis: Like nitrogen, phosphorus is essential for genetic material, enabling cell division and growth.
