उत्तर
One of the following organisms can live without oxygen of air. This organism is yeast.
Explanation:
Yeast is a facultative anaerobe, meaning it can survive completely without oxygen by switching to anaerobic respiration (alcoholic fermentation). During this process, it breaks down glucose into ethanol, carbon dioxide, and energy (ATP).
In contrast, Amoeba, Yak, and Leech are strictly aerobic organisms that require a continuous supply of oxygen from their environments to carry out respiration and survive.
