“Euglena are found in fresh and salt waters. They are often abundant in quiet inland waters where they may bloom in numbers sufficient to color the surface of ponds and ditches green (E. viridis) or red (E. sanguinea).” (wikipedia) | “Euglena are found in fresh and salt waters.

"Euglena is a mixotroph (or facultative photoautotroph): it is a photoautotrophic organism because it can utilize carbon dioxide as a carbon source in the presence of light through photosynthesis in chloroplasts and ammonium and nitrate as nitrogen sources; and it is also a heterotrophic organism because it can utilize dissolved organic compounds as carbon source.

“Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy, like plants. However, they can also take nourishment heterotrophically, like animals.” (wikipedia) | “Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy, like plants.
