Primary Production Ocean food chains begin with microscopic phytoplankton that convert sunlight into energy through photosynthesis. These tiny organisms produce about half of Earth's oxygen while forming the foundation of marine food webs. Their abundance varies with light availability, nutrient levels, and water temperature, creating patterns o
