Answer: A

Explanation: Autotroph is another word for a producer which would mean the protozoan would make its own food and wouldn’t need to feed off the WBC and bacteria. I don’t believe it would a mixotroph due to it not expressing the protozoan has any autotroph-like characteristics. Parasite are usually organisms that thrive and survive on their “host” but also harm them in the process this harm would be the cause of the STD and the loss of needed WBCs
