Answer: The given statement is False.
Sunlight is considered as a major source of energy for all life forms that are present in the ecosystem. But it is not a food resource, instead the energy from sunlight (called solar energy) is used in the formation of food through a process called photosynthesis ( that takes place in green plants and algae). The food prepared by plants is used by different organisms in the ecosystem through food chain.
