What are the photoautotrophs?

Photoautotrophs are organisms that carry out photosynthesis. Using energy from sunlight, carbon dioxide and water are converted into organic materials to be used in cellular functions such as biosynthesis and respiration

Explanation:

the example of photoautrophs are

Examples of phototrophs/photoautotroph include:

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

the fossil record provides evidence of a common ancestor to many species.
