Up to 1,00,000 organisms live on every grain of sand: Study
As many as 10,000 to 1,00,000 microorganisms live on every grain of sand, a Germany-based study has revealed. Researchers said the bacteria do not colonise the sand grains uniformly and live in cracks and depressions of the grain, which saves them from flowing water and predators who comb the grains' surface in search of food.
