Answer:
The correct answer is D. is a facultative anaerobe
Explanation:
A facultative anaerobe is the organisms that can live in the absence of oxygen but prefer to utilize the oxygen when oxygen is present in the environment.
An anaerobic organism requires more amount of energy sources like carbohydrates because they use the fermentation process to make energy and this process results in the formation of less energy than aerobic respiration.
All the bacteria of family Enterobacteriaceae that live in the intestine are facultative anaerobes. Therefore facultative anaerobe can thrive in both the presence and absence of oxygen so the correct answer is D. is a facultative anaerobe.

Among vertebrates, external fertilization is most common in amphibians and fish. Invertebrates utilizing external fertilization are mostly benthic, sessile, or both, including animals such as coral, sea anemones, and tube-dwelling polychaetes. Benthic marine plants also use external fertilization to reproduce.
