The Vital Role of Plankton in Ecosystems
Plankton are critical to Earth’s ecosystems, being the foundation of the aquatic food chain. These microscopic organisms, while often invisible, support a diverse array of marine life and play a significant role in nutrient cycling. Phytoplankton, for instance, are responsible for a substantial portion of the world's photosynthesis, converting carbon dioxide into oxygen, which is essential for all aerobic life forms. Without plankton, the ocean's complex web of life would collapse, highlighting their importance not just in marine environments but also in the wider ecological balance of the planet.
