Answer: The means for transmission of disease-causing microorganism is provided by the direct or indirect contact.
Microorganisms can cause disease only once they are transferred to the body. The disease causing microorganisms are termed as pathogens which are transmitted by several ways such as from skin to skin, by nuclei droplets, through blood and body fluids or via air. In vector transmissions the disease is carried by the parasitic insects via animals, air borne transmission occurs when microorganisms move through air or the dust particles, droplet transmission occurs by coughing, sneezing or talking by the person who is infected while indirect transmission occurs by physical contact or by touching contaminated objects.
 
        
                    
             
        
        
        
b. protozoa
One of the four species of protozoan in the genus Plasmodium is responsible for the acute or subacute infectious disease known as malaria.
<h3>A virus or a bacteria causes malaria?</h3>
- A virus or bacteria cannot cause malaria. 
- Plasmodium, a parasite that often spreads through infected mosquitoes, is what causes malaria. 
- A mosquito consumes Plasmodia that are present in blood when it feeds on an infected human.
<h3>How do protozoa cause malaria?</h3>
- The female anopheles mosquito bite is the primary method of transmission of malaria, a protozoan infection of the red blood cells. 
- The Plasmodium genus of protozoa is what causes malaria.
- Four different types of malaria parasites can infect people: Plasmodium malariae, vivax, ovale, and falciparum
