Marine snow refers to a continuous shower of mostly organic material falling from the upper layers of the ocean to the deeper layers. This material typically consists of dead and decaying phytoplankton, zooplankton fecal matter, and other organic debris, along with minerals and other particles. Marine snow plays a crucial role in the ocean's ecosystem as it provides a food source for various marine organisms, particularly in the deep sea where sunlight cannot penetrate, making photosynthesis impossible.
