Autotrophs, also referred to as self-feeders, are organisms capable of producing their own food through photosynthesis or chemosynthesis. They are the basis of every food chain and directly or indirectly feed every living organism. From green plants to certain bacteria, autotrophs channel energy from the sun or chemical reactions into accessible forms, supporting and nourishing ecosystems. Understanding autotrophs gives us insight into the complex interplay of life, shedding light on everything from climate change to food production.#16#
