Do protozoa need a host?
Protozoa do not necessarily need a host to survive, as many are free-living organisms that can thrive in various environments, such as soil, freshwater, and marine ecosystems. However, some protozoa are parasitic and require a host organism to complete their life cycle and reproduce. In these cases, the host provides essential nutrients and a suitable environment for the protozoa to live and multiply.
What is a free-living organism?

What is the difference between a virus and a bacteria in terms of remaining alive?
Viruses are not considered alive outside a host cell; they require a living organism to replicate and carry out their life processes. In contrast, bacteria are single-celled organisms that can thrive independently in various environments, obtaining energy and nutrients from their surroundings. While bacteria can reproduce on their own, viruses need to infect a host to multiply. This fundamental difference in their dependence on host cells is key to distinguishing between the two.

Why does viruses act like a parasite and find a host cell?
Viruses need a host cell to replicate and multiply because they lack the cellular machinery for these processes. By hijacking the host cell's machinery, viruses can produce more viral particles and continue their infectious cycle. This allows viruses to thrive and spread within a host organism.
