Algae, a diverse group of aquatic organisms, trace their origins to a variety of sources. Sunlight provides the energy for photosynthesis, enabling algae to thrive in both freshwater and marine environments. Nutrients essential for growth, such as nitrogen and phosphorus, are derived from natural water sources or agricultural runoff. Carbon dioxide, a vital building block for algae, is absorbed from the atmosphere or dissolved in water. Finally, warm temperatures and stable water conditions favor the proliferation of algae, making them abundant in tropical and temperate regions.
