Detailed explanation-1: -Green plants and photosynthetic bacteria are photoautotrophs. Photoautotrophic organisms are sometimes referred to as holophytic. Such organisms derive their energy for food synthesis from light and are capable of using carbon dioxide as their principal source of carbon.

Detailed explanation-2: -Oxygenic photoautotrophs such as plants, green algae, and cyanobacteria are blessed with the capacity to convert solar energy into chemical energy and releases oxygen as a byproduct; both are required for the fundamental growth of life on the earth (Kirilovsky and Kerfeld, 2012).

Detailed explanation-3: -Green plants that convert carbon dioxide into carbohydrates in the presence of sunlight are called photoautotrophs, and they are the primary producers in most marine and terrestrial ecosystems.

Detailed explanation-4: -Photoautotrophs include photosynthesizing microorganisms and green plants. Holophytic creatures are occasionally referred to as such. Photoautotrophs include a few higher plants (trees, maize plants, etc.), green algae, and cyanobacteria, phytoplanktons.
