It takes 3 days or less for some food leftovers or even just wet spots on wood in room temperature to start growing a good amount of bacteria all over it, so how is it that like all of the ground and other organic material out in the elements aren’t completely covered in mold and algae after billions of years?
In: Biology
The earth is covered in microorganisms. On regular surfaces such as the ground, there is a limited amount of resources that support life. So microorganisms are there, just in lower numbers making it impossible to see them without a microscope. If you took a q-tip and swabbed a random surface and transferred it to a Petri dish with abundant food, you’d get a nice visible colony.
