Producers are organisms like green plants and certain bacteria that can make organic compounds such as sugar and starch from inorganic substances using the radiant energy of the sun in the presence of chlorophyll. This process is known as photosynthesis.

Producers in an ecosystem are organisms that serve as the foundation of the food chain by converting solar energy into organic compounds through photosynthesis. These organisms, primarily plants but also certain bacteria and algae, are capable of harnessing sunlight to synthesize carbohydrates from carbon dioxide and water.
During photosynthesis, producers use pigments like chlorophyll to capture sunlight, which energizes electrons in the chlorophyll molecules. These energized electrons initiate a series of chemical reactions that convert carbon dioxide and water into glucose and oxygen. The produced glucose serves as an energy source for the plant and forms the basis of the food web, as herbivores consume these plants, and the energy is transferred through successive trophic levels. Ultimately, producers play a vital role in ecosystem dynamics by converting solar energy into a form usable by other organisms in the food chain.
