Final answer:
Viruses cannot find a location in or on body tissues suitable for growth because they require a host cell to replicate and multiply.
Step-by-step explanation:
The answer to the question is Viruses. Bacteria, fungi, and protozoa can find locations in or on body tissues suitable for growth.
Viruses, on the other hand, are not considered living organisms and cannot grow on their own. They require a host cell to replicate and multiply.
For example, when a virus infects a human, it enters the host cells and uses the cell's machinery to make copies of itself. These copies can then go on to infect other cells in the body.
