Question

What three kingdoms hold the most common pathogens?

Answer 1

We have that all of life is organized in 5 kingdoms. The animals and the plants are pretty straightforward; the first one contains most organisms that produce their own energy and the second one contains multicellular organisms that usually move. Fungi are a kingdom whose members are both multicellular and monocellular and they are eukaryotic. Protista are eukaryotic unicellular and Monera are prokaryotic unicellular. Most of the pathogens that we treat today are either fungi (athlete's foot) or are caused by bacteria which are contained in the kingdom of monera. A lot of protista can also be pathogens; a prime example is the disease of malaria whose cause is a protist. Viruses are also a big threat to health and are called pathogens but they do not constitute a kingdom (we do not classify them as alive). Hence, the three correct choices are Protista, Monera and Fungi.
