An organism is discovered that thrives in both the presence and absence of oxygen in the air. curiously, the consumption of sugar increases as oxygen is removed from the organism's environment, even though the organism does not gain much weight. this organism a. is a normal eukaryotic organism b. is photosynthetic c. is an anaerobic organism d. is a facultative anaerobe

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.

a. possible errors

d. new questions

explanation:

predictions and planning happen before. a summery comes after. errors you get after investigation and new questions propose what you can look for in the future.
