Answer:
Anaerobic heterotroph
Explanation:
E. histolytica It is an anaerobic parasite of the protozoan family. It's anaerobic because they can survive within the human being's organism in the absence of oxygen. It is heterotrophic because it feeds on digested food in the intestine of its guests. It also kills and degrades nearby cells to ingest nutrients.
