state one way the euglenas tow methods of nutrition provide a survival advantage the other unicellular do not.

A biology student was given three unlabeled jars of pond of water from the same source, each containing a different type of mobile unicellular organism: eugena, ameba, and paramecium are both heterotrophs and the euglena can be either heterotrophic or autotrophic, depending on its environment.

photosynthesis is a capacity euglenas have developed and amoeba and paramecium have not.
Amoeba and paramecium have mitochondria and euglenas do so, but also they can develop chloroplasts when light is present in this environment and other food source are absent. It requires a constant flow of CO2, light and water to syntetize glucose, and O2.
