Answer/Explanation: Organisms that make food through photosynthesis are classified as "autotrophs," as opposed to "heterotrophs," which must consume other organisms to make their food. The kingdoms which contain photosynthetic organisms are Monera, Protista and Plantae.
Photosynthetic organisms, known as photoautotrophs, capture the energy from sunlight and use it to produce organic compounds through the process of photosynthesis. In photosynthesis, the inorganic compounds of carbon dioxide, water, and sunlight are used by photoautotrophs to produce glucose, oxygen, and water.
