Which ecological cycle is directly driven by sunlight?

Solution(By Examveda Team)

The ecological cycle that is directly driven by sunlight is Hydrologic.
The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
The hydrologic cycle involves the continuous circulation of water in the Earth-Atmosphere system. This cycle is powered by the energy emitted by the sun. This energy heats water in the ocean and seas. Water evaporates as water vapor into the air. Some ice and snow sublimate directly into water vapour.
