Final answer:
An obligate anaerobe cannot be cultured in a candle jar because it requires oxygen-free conditions for survival and growth.
Step-by-step explanation:
The subject of question is science.
An obligate anaerobe is an organism that cannot survive or grow in the presence of oxygen. These organisms require special conditions for culturing, such as an anaerobic jar or chamber that removes oxygen from the environment. A candle jar, on the other hand, is not suitable for culturing obligate anaerobes as it does not provide the necessary conditions.
