What is light in ecology?

Light energy affects water temperature, biological processes (such as the relationship between predators and prey) and plant photosynthesis and growth. Under natural conditions light is controlled by topography, cloudiness, vegetation cover, and seasonal patterns, like less daylight in the winter.

What is sunlight in ecosystem?

Sunlight plays an important role in the ecosystem. It is the primary source of energy, which is utilised by plants to produce food and required for productivity and energy flow in the ecosystem. Visible spectrum of sunlight is used by plants for photosynthesis.
