Another name for autotrophs is “producers.” Autotrophs are organisms that produce their own food from inorganic substances, typically through the process of photosynthesis or chemosynthesis. This ability places them at the base of the food chain, as they can convert sunlight or chemical energy into organic compounds which are then available for consumption by other organisms. In ecosystems, producers support a wide variety of life forms, making them essential for energy flow and nutrient cycling.
