Plankton

플랑크톤

Definition

Microscopic organisms that drift in water columns, forming the foundation of aquatic food chains.

Detailed Explanation

Phytoplankton are responsible for approximately 50% of global oxygen production and fix as much carbon annually as all terrestrial plants combined. Zooplankton transfer this energy to fish and marine mammals. Plankton distributions are shifting poleward as oceans warm, altering food web timing and structure. Satellite remote sensing of ocean color tracks phytoplankton blooms, providing global estimates of ocean productivity.
