Answer
B. burgdorferi is the bacterium that lives in the body and is called endoparasite, while ticks are the carrier of B. burgdorferi and live on the body surface of their host and are called ectoparasites. Thus option (a) is the correct answer.
Work Step by Step
The Borrelia burgdorferi (B. burgdorferi) is an endoparasite and the tick is an ectoparasite. B. burgdorferi is the bacterium that is transferred into the body of humans by the ticks. This bacterium causes Lyme disease. Since this bacterium lives inside the human body and acts as a parasite, it is an endoparasite.
Whereas the ticks, on the other hand, live on the body surface of the humans. They are blood-sucking parasites that harvest nutrients for their survival by sucking the blood of humans. So, they are ectoparasites.
