Answer:
scavengers, predators, decomposers
Answer: The correct answer is option C.
Explanation:
A false negative test is a diagnostic error in which a test shows absence of a disease even when a person is having a disease.
Similarly, in the given question a sample has anthrax spores; however, antibody test fails to show the presence of anthrax. Thus, it is a false negative.
