Question

An organism that makes its food from light

Answer 1

An organism that makes its food from light is called a photoautotroph. The most common examples of photoautotrophs are plants, algae, and certain bacteria, such as cyanobacteria. These organisms utilize photosynthesis to convert sunlight, water, and carbon dioxide into glucose (a form of sugar) and oxygen. This process not only provides energy for the organisms themselves but also contributes to the oxygen content of the atmosphere, which is essential for the survival of most life forms on Earth.
