phytoplankton productivity

Phytoplankton are tiny, plant-like organisms that float in the ocean's surface waters. They perform photosynthesis, using sunlight to produce energy and grow, similar to land plants. This process releases oxygen and forms the foundation of the marine food web, supporting fish, whales, and other sea life. Phytoplankton productivity refers to how effectively they convert sunlight and nutrients into biomass (growth). Factors like sunlight, nutrient levels, and water temperature influence their productivity. Overall, phytoplankton play a critical role in regulating Earth's oxygen, carbon cycle, and sustaining ocean ecosystems.
