Sunlight
The direct source of energy for phototrophs is light. They use light energy to convert carbon dioxide and water into glucose through a process called photosynthesis.

Autotrophs can be phototrophs or lithotrophs (chemoautotrophs). Phototrophs use light as an energy source, while lithotrophs oxidize inorganic compounds, such as hydrogen sulfide, elemental sulfur, ammonium and ferrous iron.
No, chemotrophs and phototrophs are not the same. Chemotrophs obtain energy by oxidizing chemical compounds, while phototrophs harness energy from sunlight through photosynthesis. Both are types of organisms that produce energy, but they utilize different sources—chemical versus light energy.

Phototrophs are organisms that obtain energy from light through photosynthesis. Examples include plants, algae, and cyanobacteria, all of which use sunlight to convert carbon dioxide and water into glucose and oxygen. Additionally, some bacteria, such as purple and green sulfur bacteria, are also classified as phototrophs, utilizing light energy for their metabolic processes.
Autotrophs that utilize light as their energy source are called phototrophs. These organisms are able to perform photosynthesis to convert light energy into chemical energy for their survival and growth. Examples include plants, algae, and some bacteria.
One example is the sun.
Phototrophs, such as plants and algae, use sunlight to convert carbon dioxide and water into glucose through photosynthesis. Heterotrophs, including animals and fungi, consume organic matter produced by phototrophs to obtain energy. When heterotrophs respire, they release carbon dioxide back into the environment, which can be taken up by phototrophs to fuel photosynthesis, closing the cycle.
In fission reactors, which is the only practicable source of energy at present, it is the fission of the nuclei of uranium and plutonium which produces the energy

Energy released from movement of protons through ATP synthase energy released from movement of protons through ATP synthase is the most direct source of energy in this case.
