The metabolism of the following organisms belongs to heterotrophic anaerobic type: () A. Porphyra B. Grasshopper C. Escherichia coli D. Mushrooms in the intestine.
A. Porphyra has chlorophyll, which can be used for photosynthesis, and its nutrition mode is autotrophic.

B, locusts are heterotrophic animals, breathing under the action of oxygen, decomposing organic matter in the body.

C. Intestinal Escherichia coli has no chloroplast, and its nutrition is heterotrophic. It is an anaerobic organism parasitic in human intestine.

D. The basic structure of mushroom is cell wall, cell membrane, cytoplasm, nucleus and vacuole, and there is no chloroplast. Therefore, it cannot carry out photosynthesis and must rely on ready-made organic matter to maintain life. Therefore, the way of nutrition is heterotrophic saprophy, which is an aerobic organism.

So choose: C.
