    Solution

    Autotrophs are organisms that can produce their own food using energy from sunlight (photosynthesis) or from inorganic compounds (chemosynthesis). In the grazing food web, autotrophs, such as plants or algae, form the base of the food chain. They convert sunlight or inorganic nutrients into organic matter through photosynthesis, making energy available to other organisms in the ecosystem.
