Previously euglenoids were placed in plant kingdom due to their photosynthetic ability. But due to the absence of cell wall and animals like nutrition some scientists placed them in animal kingdom. But now according to five kingdom classification they are included in Protista.
They are found as free living organisms in fresh water lakes, ponds, etc. But some times they are also found in damp soil and brackish water.
On the basis of their mode of nutrition they are called as mixotrophic because they have holophytic, holozoic and saprophytic mode of nutrition.
