A Single Drop of Seawater Holds Billions of Microscopic Lives
One tiny droplet of ocean water can contain up to one billion individual organisms, including tiny plankton, bacteria, and viruses. These hidden ecosystems drive the planet’s oxygen cycle and form the base of the entire marine food web. Scientists now know that such micro-life forms are so abundant they outnumber all the stars in the Milky Way.
💡 Fun detail:
If you could line up every microbe in one drop end to end, the chain would stretch the length of several football fields.
