ANS . ALL OF THE ABOVE
Some pathogens are parasitic, live 1/1 on or inside another organism and use the organism’s nutrients for their own survival and cause various diseases. This an example of
•bacteria
• fungi
• protozoa
• virus
PROTOZOA
Pathogen cause infection must enter the cells of other living beings and use the cell’s machinery to make a copy of themself.
