Drifters, or planktonic organisms, play a significant role in marine food webs as they serve as primary producers and food sources for a variety of marine animals. These organisms, including phytoplankton and zooplankton, drift with ocean currents and form the basis of the aquatic food chain. They convert sunlight into energy through photosynthesis and, in turn, provide nourishment for larger marine organisms, such as fish and whales. Understanding their role is crucial for studying marine ecosystems, biodiversity, and sustaining fishery resources.
