Answer:

Facultative anaerobe

Explanation:

A facultative anaerobe is an organism that commonly grow in the presence of oxygen and use aerobic process to form ATP and to gain energy but they can also grow in the anaerobic condition by getting energy from fermentation process.

As anaerobic condition is not the perfect condition in which facultative anaerobe wants to grow because they prefer more to grow in aerobic conditions, therefore, their growth is not that much high in anaerobic condition as compared to aerobic conditions.  

Therefore they show moderate growth in the culture present in candle jar and anaerobic jar because oxygen is absent there but show heavy growth in the culture present in a standard incubator because of the presence of aerobic condition here.
