Higher plants (maize plant, trees, grass etc)
Euglena.
Algae (Green algae etc)
Bacteria (e.g. Cyanobacteria)
Algae are photoautotrophs found in most ecosystems, but they generally are more important in water-based, or aquatic, ecosystems. Like plants, algae are eukaryotes that contain chloroplasts for photosynthesi
