How do plants turn sunlight into food?
Photosynthesis doesn't necessarily turn sunlight into food. Rather, it turns carbon dioxide and water into food, using sunlight as the energy to perform this process.
Plants do not just help, they are ESSENTIAL to life on Earth. All living things need energy to live (food). The source of the energy in food is Sunlight and the ONLY organisms on Earth that can trap this sunlight and turn it into food are Plants. Plants therefore form the base of the food chain for all living things on Earth.
Energy enters a food web thorough plants in the form of sunlight energy. Plants use sunlight energy to turn water and carbon dioxide into plant food. When animals and human beings consume plant produce like carrots, beetroots, beans, cabbage, grams etc, the energy enters the food web through plants.
Green plants use a process called photosynthesis to make food from sunlight. Only green plants can make their own food. Other plants (like mushrooms) and animals do not make their own food, but get nutrition from green plants (or dead green plants). Animals do not make food from sunlight. If they could, they would not need to eat.
