Which organism has the greatest ability to reproduce?

It is impossible to single out an organism that has a greater ability to reproduce. This is due to the fact that not all organisms are fully investigated and not all have been discovered. But we can say that mushrooms multiply very quickly. This is especially true of moldy mushrooms. Thanks to the millions of spores that a single mushroom produces, they take over territory very quickly. Molds are found almost everywhere except in very cold, hot and dry areas. Also, bacteria have a fast reproduction rate during division.
