"Sunlight is necessary for photosynthesis."

Photosynthesis uses solar energy to fix carbon dioxide into organic matter, driving the carbon and oxygen biogeochemical cycles.

(Briefly: burning fossil fuels releases CO2 and alters the carbon cycle but isn't the fundamental energy input for the cycle; nuclear fusion and the statement about animals getting energy directly from the sun are incorrect in this context.)
