The Sun is a primary source of energy for all life on Earth. But it’s not food by itself. It aids plants to produce sugars and carbs by converting sunlight into carbon dioxide and sugar. Without sunlight, plants would not be able to survive. Plants also need energy to grow. They obtain energy from sunlight, and that is why they use it to grow. However, sunlight does not provide energy to all living organisms.
Algae and plants transform sunlight into food in all of the world’s ecosystems. These producers in the food web are the main energy source of the food chain. Plants and algae undergo photosynthesis, converting sunlight into sugar. These plants then release carbon dioxide and water, producing sugar in the process. They also produce oxygen as an byproduct. Sunlight provides energy to these producers, who in turn transfer it to other organisms in the food web.
Photosynthesis is the process by which plants create biomass. Chlorophyll is a pigment that absorbs certain wavelengths of light and converts it into organic matter. Many organisms use this carbon dioxide and water-based energy to obtain food and other resources. The carbon dioxide and water in the air are used as the source of energy in hydrothermal vent ecosystems. The total energy available determines the overall productivity of an ecosystem.
