Can a euglena survive on its own

Answer 1

Yes, Euglena can survive on its own as they are single-celled organisms capable of performing photosynthesis. They possess a flagellum to move around and can create their own energy through photosynthesis by harnessing the power of sunlight. Euglena can also survive in environments without sunlight by obtaining nutrients from their surroundings through phagocytosis, a process in which they engulf and consume smaller particles or organisms.
