Accepted Answer

Facultative organisms are those that have the ability to live in a wide range of conditions or environments. They can adapt to different conditions and can switch between different modes of metabolism depending on the availability of resources. For example, certain bacteria can switch between using oxygen or other inorganic compounds as electron acceptors depending on the presence or absence of oxygen in their environment.
